Test your WordPress Webhost’s Performance with WP Performance Tester

Article by Erlend Eide. Published on February 19, 2018

Have you tested how fast your WordPress host really is? How can you know what to expect from your hosting? To test the server and database performance, you can install a simple plugin called WP Performance Tester.

In this article we have tested two of our standard servers used for all our standard WordPress plans.

Install and run WP Performance Tester

You can download the plugin here or if you can install it via WP-CLI (much easier!) run this command:

$ wp plugin install wpperformancetester --activate

After installation you can find a menu item under Tools > WP Performance Tester.

Click the “Begin Performance Test” button, and wait until it prints the results (around 7-10 seconds on our servers).

The plugin does not test the performance of your particular WordPress installation, but tests how fast the server processes a variety of server tasks required to deliver your webpage.

Analyzing the Performance Benchmark Results

The important reference values to keep an eye on are:

  • Total Time under Server Performance Benchmarks (PHP Bench)
  • WordPress Performance Benchmark (WP Bench) – queries per second

The following is an example from one of our standard, highly scalable, servers. Highly scalable servers have slight disadvantage compared to servers with higher frequency CPUs, but will be able to deal with way more simultaneous traffic.

As you can see from the graph, our servers are finely tuned to deliver WordPress at an amazing speed – compared to all other hosts.

Lower graphs are better!

The green summaries are the numbers that are comparable and really matter.

We also provide less scalable hosting that produces even better numbers, like this one:

So how does this compare to other hosting providers?

Reviewsignal.com publishes numbers for many other hosting providers. Unfortunately, we did not submit for testing – but we’ll make sure to participate next year!

Servebolt’s performance from the two random test above are

PHP Bench WP Bench
Servebolt.com Standard 8.445 1412.4
Servebolt Mini Dedicated 6.741 2092.0

For PHP Bench, lower numbers are best (fastest execution time)
For WP Bench, higher numbers are best (most queries per second)

Other hosting providers performance from Review Signal’s 2018 test

PHP Bench WP Bench
Kinsta 8.787 1207.7
Presslabs 7.215 823.0
WordPress.com VIP 9.18 798.1
Pressable 10.924 529.1
Nexcess 11.687 450.0
WP Engine 10.766 418.4
Pantheon 8.708 235.9
SiteGround 10.457 196.6


As you can see from the table we outperform every enterprise host tested in terms of database performance for both tests. Lacking database performance is usually what makes WordPress and WooCommerce slow.

Install the plugin, test your host – and submit an honest review! We’d love to hear about what numbers your host produces in the comment field!
