The speed and responsiveness of your website are critical to your business success. When a user clicks on your website, they expect a swift, smooth experience. This is where server response time comes into play – an essential yet often overlooked aspect of website performance.
Slow server response times test the patience of your audience and have a tangible impact on your site’s overall speed. This, in turn, can lead to higher bounce rates, where visitors leave your site prematurely, and can even negatively affect your rankings on search engines like Google.
🤔 But what exactly is server response time?
Put simply, the server response time is the duration between a browser requesting a page and the server responding to that request.
Imagine it as a conversation between two friends – if one takes too long to reply, the flow of conversation suffers. Similarly, with websites, a delayed response from the server can disrupt the user’s experience.
WordPress is not immune to these challenges. Several factors can bog down WordPress sites, such as subpar hosting services, outdated PHP (Hypertext Preprocessor) versions, bloated databases, and inefficient caching. Each of these elements can add unnecessary weight to your website’s server response time.
This article will uncover eight practical and easy-to-implement tips to trim down server response times, enhance your site’s speed, improve the user experience, and boost your Search Engine Optimization (SEO) rankings!
Introduction to Time to First Byte (TTFB)
A key player in web performance is Time to First Byte, or TTFB. Imagine you’re at a cafe, and you’ve just ordered a coffee. TTFB is akin to the time it takes for the barista to start pouring your coffee after you’ve placed your order.
In web terms, TTFB is the time from when you click on a webpage to when your browser receives the first piece of data from the server. It’s the initial signal that something is happening behind the scenes.
TTFB is an important metric for measuring the responsiveness of your web server and other network resources. It helps you understand how efficiently your site communicates with its server.
Let’s break down what happens when you request a page:
- Your request is directed to the right server via a DNS lookup.
- The server processes your request. This involves loading scripts and accessing databases – essentially preparing the response.
- The server sends back the first byte of data, marking the end of the TTFB phase.
This process might seem technical, but it’s essential for WordPress users to understand it because each step – from DNS lookup to server response – can be optimized for better performance.
High TTFB can slow down your website, frustrating users and affecting your site’s SEO rankings negatively. However, it’s important to note that Google has stated TTFB is not a primary ranking factor. So, while it’s vital, it’s part of a broader puzzle of website optimization.
What’s a good TTFB?
It’s generally recommended to aim for a TTFB under 800 milliseconds. Achieving this involves several factors:
- The quality of your web hosting.
- How your server is configured.
- Network latency.
- The amount of traffic your site receives.
Each of these can either speed up or delay that first byte from reaching your browser.
Top 8 tips for reducing WordPress server response time
1. Upgrade your hosting
You know the old saying, “You get what you pay for”? Well, it rings especially true in the world of web hosting.
The first and perhaps most impactful step you can take to reduce server response time is to upgrade your hosting because that is the foundation of your website. Just like a sturdy foundation is necessary for a building, a robust hosting service is essential for your website’s speed and reliability.
It’s tempting to go for cheaper hosting options, especially when you’re just starting out. But here’s the catch: many budget-friendly hosting providers use shared servers. This can lead to slower response times because your site is essentially competing with many others on the same server for bandwidth and processing power.
✔️ That’s why we at Codeable recommend premium hosting services from providers such as Kinsta and WP Engine.
These two web hosting providers specifically specialize in WordPress hosting and offer dedicated resources, which means more room for your website to breathe and less competition for resources. With a WordPress-optimized infrastructure, Kinsta and WP Engine provide better caching, faster databases, and a more streamlined experience for your site visitors.
2. Enable caching
Caching stores copies of your website’s files so they don’t reload from scratch every time someone visits your site. This dramatically reduces server response time, making your website faster and more efficient.
There are several types of caching, each serving a unique purpose:
Browser caching
When someone visits your website, elements like images, stylesheets, and JavaScript files are downloaded and stored in their browser’s cache. The next time they visit your site, instead of downloading these elements all over again, the browser loads them from the cache. This significantly reduces load times and bandwidth usage.
Page caching
When a user requests a page, WordPress dynamically generates an HTML file based on PHP scripts and database calls. Page caching saves this generated HTML file and serves it for future requests.
This means the server doesn’t have to go through the entire page generation process each time, which reduces the workload and speeds up response time. It’s particularly useful for content that doesn’t change frequently.
Object caching
Every time a page is loaded, several database queries are run. Object caching saves the results of these queries in memory.
When the same piece of data is requested again, it can be served from the cache rather than querying the database once more. This is like keeping a notepad of frequently asked questions and their answers; you don’t have to look up the information each time it’s requested.
Database caching
Similar to object caching, database caching specifically focuses on caching the results of complex database queries, so the time taken to retrieve data is significantly reduced, enhancing the overall response time of your site. This is especially beneficial for websites with large databases or those that perform complex queries.
Opcode caching
PHP scripts are executed to generate web pages. With opcode caching, these scripts are compiled into bytecode and stored in memory. This means the PHP interpreter doesn’t have to compile these scripts every time a request is made, leading to faster execution and response times.
To implement caching on your WordPress site, you can use plugins like WP Rocket and W3 Total Cache. These are two of the most reliable caching plugins out there, offering a range of features to handle different types of caching needs.
📎 We aren’t affiliated with these plugins, but we recommended them based on their functionality and popularity in the WordPress community.
3. Use a Content Delivery Network (CDN)
A CDN is a network of servers scattered across the globe, each storing a copy of your website. When someone visits your site, the CDN delivers the content from the nearest server location. This reduces the distance the data has to travel, making your website faster and more responsive, especially for international visitors.
Two popular CDN options stand out: Cloudflare and MaxCDN (now StackPath).
Cloudflare serves content from nearby servers and provides security features to protect your site from attacks. It’s user-friendly and offers a free plan, which is a great starting point for small to medium-sized websites.
Stackpath is known for its high performance and is particularly effective for websites with heavy traffic or large files. While it doesn’t have a free plan like Cloudflare, it’s a strong choice for larger businesses or websites looking for an extra boost in speed.
Using a CDN ensures that no matter where your visitors are in the world, they can enjoy a fast and smooth experience on your site.
4. Compress your site files
Compressing your WordPress files reduces their size, making them quicker to transfer from the server to the user’s browser, which is vital for improving server response time.
One popular method of compression is using gzip – a digital compression tool that shrinks the size of your site’s files without losing any content or quality.
Enabling gzip is relatively straightforward, but remember, it’s always good to back up your site before tinkering with system files.
- You need SSH access to your server. This can typically be done through a terminal or command prompt. Use a command like:
| ssh username@yourserver.com |
Replace username with your actual server username and yourserver.com with your server’s address.
- Once logged in, use the cd (change directory) command to navigate to the directory where your WordPress files are located. For example:
| cd /path/to/wordpress |
- You can compress a single file with this command:
| gzip filename |
You can also compress an entire directory using this command:
| gzip -r directoryname |
The -r flag is for recursive, meaning it will compress all files in the directory and its subdirectories.
Apart from gzip compression, you can minify CSS and JavaScript files by removing unnecessary characters (like spaces and line breaks), which will reduce file size and minimize the number of requests your server has to handle.
There are several tools and plugins for minification. Autoptimize and WP Super Minify are popular choices.
5. Update your website and extensions
Just like any software, WordPress regularly releases updates, which don’t just add new features. They often include optimizations that can speed up your site. So, make sure to keep your WordPress core up-to-date.
Themes and plugins must also be updated periodically to ensure they perform at their best, contributing to a faster server response time. However, before updating, always back up your site – if something goes wrong, you can always restore to the previous state.
6. Update your PHP version
PHP, the programming language that powers WordPress, regularly releases new versions. These newer versions are optimized for faster performance, making your site process requests more quickly and noticeably decreasing the server response times.
However, upgrading PHP isn’t something to rush into – check that your WordPress theme and plugins are compatible with the newer PHP version first. This is necessary because using outdated themes or plugins with a new PHP version can lead to compatibility issues that might break your site or cause unexpected behavior.
The process usually involves testing in a staging environment first. This way, you can guarantee that everything works smoothly before applying the changes to your live site.
7. Optimize your database
The efficiency of your database directly impacts your server’s response time. Over time, WordPress databases can accumulate a lot of unnecessary data — things like transients (temporary data), old plugin data that are no longer needed, and an excess of post revisions. The more cluttered and unorganized, the slower your website responds to requests.
So, what does database optimization involve? Let’s break it down:
- Cleaning up transients: These are temporary options stored in your database. They’re useful but can pile up over time. Regularly clearing them out keeps your database efficient.
- Getting rid of old plugin data: When you uninstall plugins, they don’t always clean up after themselves. They can leave behind tables and entries in your database.
- Limiting post revisions: Every time you save a draft, WordPress creates a revision. This feature is helpful for rolling back changes, but too many revisions can bloat your database.
You can clean up your database manually or use plugins like WP-Optimize or WP-Sweep. These plugins can remove unnecessary data and organize what’s left to significantly reduce the load on your server, leading to quicker response times.
8. Reduce page bloat by deleting unnecessary plugins
Plugins are fantastic tools that extend the functionality of your WordPress site. However, each plugin, no matter how small, adds a bit of load to your server.
This can be in the form of extra HTTP requests, additional database queries, or even conflicting scripts. The more plugins you have, the heavier the load, resulting in longer server response times and a sluggish user experience.
Regularly audit your plugins and ask yourself, “Do I really need this?”. Here are some tips for assessing your plugins:
- Check for redundancy: Sometimes, multiple plugins serve similar purposes. Do you have two SEO plugins when one would be enough?
- Assess usage: If there’s a plugin you haven’t used in a while or that serves a purpose that’s no longer relevant, it’s probably time to let it go.
- Evaluate performance impact: Some plugins are more resource-intensive than others. There are tools available that can help you identify which plugins are slowing down your site, like Query Monitor or P3 (Plugin Performance Profiler).
- Consider alternatives: If a plugin is necessary but heavy on resources, look for lighter alternatives that can achieve the same function without the bloat.
Each of these tips, though seemingly small on its own, contributes to a significant improvement in how quickly and efficiently your site communicates with its server and delivers content to your audience.
💡 Remember, the tips outlined here provide a solid foundation, but the journey to a high-performance website is ongoing. Staying ahead requires regular maintenance, updates, and optimizations.
