Measuring database performance in MySQL

Hi internals! I am currently working on an RFC draft to disable prepared statement emulation for MySQL by default. I understand this has been discussed previously[1][2], and one major concern is performance with reused statements if prepared statement emulation is disabled because of the extra round-trip. With MySQL 8.0, prepared statement reuse can be faster. My question: does anyone know of any code for testing database performance in PHP, that could be used to measure changes between older version of MySQL and newer versions? Thanks in advance, Tiffany Taylor [1] https://externals.io/message/60841 [2] https://externals.io/message/88018
