7 Practical Tips for WordPress VPS Optimization

So, you’ve got a VPS hosting plan! Congratulations on that. There are a few practical things you can do to optimize the benefits of VPS. Here, we explain 7 useful tips you can utilize for WordPress VPS optimization. 

VPS represents a form of virtualization that divides a physical server into multiple virtual servers. It’s like you are sharing an island with other natives, but your area is fenced off from everyone. VPS offers better privacy, security, and dedicated resources than shared hosting. This means you can tune up your site to take maximum advantage from your VPS hosting plan. 

Here we go.

Tip No. 1: Right Amount of Bandwidth and Storage

The first thing you must ensure with your VPS is that you have opted for the right amount of bandwidth and storage. Now, what is the right amount? Right is subjective. It totally depends on the kind of website you are having and the variables associated with that. Some of these variables include traffic, website speed, size, data handled onsite, among others.

To give an idea about the right amount of bandwidth you need, consider analyzing the data for bandwidth data of the past year for your site. You will get an idea of the pattern. There will be times where the bandwidth will be exceeded, and at other times it will be utilized very less. Observe these peaks. Now take a note of the average bandwidth consumed. With these three points, you can quickly see how your bandwidth needs vary. It would help if you opted for the bandwidth that can optimally run your site without crashing. Also, don’t opt for a costlier (and therefore with too much bandwidth) plan either. Strike a balance between cost and space so that you find what’s just right for you. 

Storage is another case. While past analysis is helpful for bandwidth, storage needs anticipation of the future. How much storage are you going to need in the next 6 months, 12 months, and a year and a half? What content are you planning to put on your website? What are your plans with your website? A practical plan will give you an idea about the storage need you will have in the near future. Again, the storage required should not be too huge and too moderate. Leave space for expansion but not too much, not too little. Avoid extremes, and you should be fine. 

Tip No. 2: Find the Right Servers

The performance of your VPS is totally dependent on the server it is running on. Cheap VPS plans come with poor server combinations, and with premium ones, you enjoy proper configuration. With premium managed WordPress hosting of Nestify, you never have to worry about server configuration. The expert team of engineers at Nestify takes care of VPS optimization. 

Make sure you check the following points:

  • Linux
  • NGinx
  • SSD
  • MySQL (5.6 or higher)’
  • PHP 7 or higher

Ensure you have the right servers with you, and you are already halfway ahead of your competitors.

Tip No. 3: Keep WordPress Updated

WordPress periodically releases updates for WordPress core. This includes many fixes and security features. Make sure you keep WordPress updated on your site. This will definitely help you to keep your VPS optimized for your website. 

Also, make sure all the plugins and themes you use are updated. Security issues with older versions of plugins can hamper the optimal functioning of your website. 

Running your site with the latest PHP and MySQL can bring performance boost not offered by earlier versions. 

Tip No. 4:  Keep Sufficient Memory

Your website may be complex or simple. It runs on processes that take up memory. If you think your site deserves more memory than what is allocated, then you should definitely check your memory allocation. Expanding memory can do the trick. 

You can change the memory allocation setting in WordPress. 

To do this, locate the wp-config.php file.

Once you open the file, locate the line /* That’s all, stop editing! Happy blogging. */

Now, just above this line, add the following line: 

In place of ‘enter the memory limit’, you can add 128M, 256M or 512M as per your need. 

Tip No. 5: Use Server Targeted Caching

Apart from leveraging browser caching, you can try your hand at server targeted caching. 

There are a couple of caching engines available. 

Some of these are as follows:

Varnish Cache
Varnish Cache is a caching HTTP reverse proxy. It is a kind of web application accelerator. It can speed up delivery up to 300 – 1000 times, depending on server configuration. It is bound by the speed of the network. 

Memcached is a memory cache daemon. It is a high-performance, distributed memory object caching system. It speeds up dynamic web applications by alleviating database load. Memcached is free and open-source. 

You can download Memcached from GitHub. 


OPCache works for sites that run on PHP. OPcache improves PHP performance. It stores precompiled script bytecode in shared memory. Thus, removing the need for PHP to load and parse scripts on each request.

Tip No. 6: Optimize Robots.txt

You can limit how bots function on your site by optimizing the Robots.txt file on your website. 

Add the following code in the robots.txt file at the root:

Now, in place of ‘number of seconds,’ you can add the time after which the bot can make next request (3600 i.e., one hour can be useful for most sites)

Tip No. 7: Disable Hotlinking

Hotlinking is a method by which the images on your website can be sourced by url. Thus, it puts a tremendous load on your server if a lot of images on your website are hotlinked on a website with high traffic. 

You can disable hotlinking by using security plugins for WordPress. Some of these provide hotlinking protection. You can check our look at 10 WordPress Security plugins for 2020
