Profiling with Blackfire
0 likes377 views
This document discusses profiling code performance with Blackfire. Blackfire is a performance management solution that instruments code to generate runtime data about its behavior and performance. It can be used as a profiler to measure and analyze application performance, debug performance issues, and automate performance testing. Profiling with Blackfire examines the wall time, CPU time, and I/O time of code, including the differences between inclusive and exclusive time measurements. The document concludes with a reminder that Blackfire can demonstrate these profiling capabilities through a demo.
