Blackfire

Blackfire, the performance analyzer that digs deep into where server resources are most used (Time, I/O, Memory, etc.), provides unequaled visualization for interpreting performance profiles.

Blackfire's interactive UI gives pinpoint intelligence about your applications' performance. Intuitive navigation rapidly drills through function calls, shows the hot paths along different cost dimensions and allows callgraph comparisons thus enabling you to understand the performance implications of your development iterations.

Blackfire is designed for development and production servers.
