About Code Profiler
From the official readme · v1.9.6Description
A profiler to measure the performance of your WordPress plugins and themes.
Code Profiler helps you to measure the performance of your plugins and themes at the PHP level and to quickly find any potential problem in your WordPress installation.

It displays many useful additional information such as database queries, file I/O operations and disk I/O usage as well.
