CPU performance testing: 
This plugin does various calculations and string manipulations on your PHP webserver 
and your MySQL database server. To further test the MySQL server, a sequence of MySQL 
inserts, selects, updates and deletes are performed in a separate custom database table 
(we do not use your WordPress tables for this).
Network testing: 
The network is tested by fetching directly from Google’s CDN / apis network. Fetching from the Google 
apis network gives you the nearest server, and will give more accurate results. We also fetch a small 1Mb 
file from our servers as well in case the Google apis is down. The network tests are not yet shown in the 
graphs, we are working on this 🙂
Results: 
After the sequence of tests has finished, the results will be displayed for you to evaluate. MySQL results can 
vary depending on the type of connection your webserver has to the MySQL server. If a “local socket” connection 
is used a typical result for the MySQL query test is 0.05-0.25 seconds. Web hosting providers with dedicated MySQL 
servers will show a slower time/queries per second, as a TCP/IP connection to the MySQL server is made instead of 
a local socket connection.
There are many factors that will determine how fast your website will run. This plugin does not test 
for how many hits/requests per second your provider allows to your website, file system performance is not tested 
either. Use it as a performance test to assess how fast a CPU your provider has allocated to your webserver 
and your MySQL database backend.
Share with your friends, let’s start a competition and see who’s got the fastests servers (hint) 🙂

PHP/MySQL CPU performance statistics

Benchmarks PHP and MySQL and does various performance analysis on these. Especially MySQL analysis is good.

In general benchmarks are short, but quite informative.

Works well and does various important tests

I had to measure the performance of my two local machines (a laptop and a desktop). This plugin came in handy to do exactly that. I only wish that there was a way to export the results for future ref!

Handy

With the performance test plugin you can test the CPU and MySQL speed on your webserver and your MySQL server.

WPPerformanceTester was written as a tool to benchmark WordPress in the <a href="http://reviewsignal.com/blog/2015/07/28/wordpress-hosting-performance-benchmarks-2015/" rel="nofollow ugc">WordPress Hosting Performance Benchmarks (2015)</a> by <a href="http://reviewsignal.com" rel="nofollow ugc">Review Signal</a>. Current benchmarks are on <a href="https://wphostingbenchmarks.com" rel="nofollow ugc">WPHostingBenchmarks.com</a>. It was designed to test the server’s performance by stressing PHP, MySql and running $wpdb queries.
WPPerformanceTester performs the following tests
<ul>
<li>Math – 100,000 math function tests</li>
<li>String Manipulation – 100,000 string manipulation tests</li>
<li>Loops – 1,000,000 loop iterations</li>
<li>Conditionals – 1,000,000 conditional logic checks</li>
<li>MySql (connect, select, version, aes_encrypt) – basic mysql functions and 5,000,000 AES_ENCRYPT() iterations</li>
<li>\$wpdb – 250 insert, select, update and delete operations through \$wpdb</li>
</ul>
It also allows you to see how your server’s performance stacks up against our industry benchmark. Our industry benchmark is the average of all submitted test results.
<h3>Notes on Performance</h3>
Performance can be measured in a lot of ways. WPPerformanceTester was simply one component of a much larger performance benchmark. It tests a single server (or node) that it is running on. So if you’re considering looking at the results from a clustered or distributed setup, it may give you limited insight into how well your whole system performs. WPPerformanceTester is about the raw speed a system has to execute code and perform database operations.
Real website performance isn’t always correlated with raw speed. A seemingly slow website could have a very fast WPPerformanceTester result. There are lots of layers (namely caching) in making a WordPress website fast. A good caching layer will almost always outperform computing power. But when the caching layers are equal, raw speed can make a difference.
WPPerformanceTester is simply one tool to add to your toolkit in measuring performance. You should have a variety of others to test other facets of performance.
<h3>Known Issues</h3>
If the script times out (max_execution_time limit) it will not show any results. You can solve this by increasing the max_execution_time in the php.ini. Some plugins may also cause WPPerformanceTester to run exceptionally slow and make it more likely to hit this limit. One such plugin is VersionPress. You can temporarily disable plugins that might be interfering with it as an alternative way to run it.
<blockquote>
Note:
<ul>
<li>It’s always best to BACKUP EVERYTHING before running ANY new plugin or making changes to your WordPress install.</li>
</ul>
