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.

2.0.1

(April 23, 2024) Minor security update.

Patched CVE-2023-49844. This vulnerability allowed a CSRF which could have let an attacker make an admin to run benchmark unknowingly.

2.0.0

(December 29, 2021) Major update and version change.

Plugin should now be compatible with latest PHP 8 / MySQL 8.

Benchmarks no longer comparable between versions. Industry benchmarks will only show results from the same version.

benchmark script updated to replace deprecated/broken math functions and mysql functions. Version number in benchmark script reflects version number of current open source library it was based on, NOT WPPerformanceTester version number.

ENCODE() replaced with AES_ENCRYPT to perform mysql benchmark.

Benchmark graph now uses Chart.js 3.7 instead of 1.x which hopefully helps conflicts with other newer plugins.

1.1.1

(Oct 1, 2021) Minor bug fixes.

1.1
