WPPerformanceTester for WordPress

WPPerformanceTester was written as a tool to benchmark WordPress in the WordPress Hosting Performance Benchmarks (2015) by Review Signal. Current benchmarks are on WPHostingBenchmarks.com. It was designed to test the server’s performance by stressing PHP, MySql and running $wpdb queries.

WPPerformanceTester performs the following tests

Math – 100,000 math function tests

String Manipulation – 100,000 string manipulation tests

Loops – 1,000,000 loop iterations

Conditionals – 1,000,000 conditional logic checks

MySql (connect, select, version, aes_encrypt) – basic mysql functions and 5,000,000 AES_ENCRYPT() iterations

\$wpdb – 250 insert, select, update and delete operations through \$wpdb

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.

Notes on Performance 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.
