Google Performance Tools

Google Performance Tools

The fastest malloc we've seen; works particularly well with threads and STL. Also: thread-friendly heap-checker, heap-profiler, and cpu-profiler.

We've Moved!

Google Perf Tools is now hosted at code.google.com. Our new homepage is located at http://code.google.com/p/google-perftools.

Overview

Perf Tools is a collection of a high-performance multi-threaded malloc() implementation, plus some pretty nifty performance analysis tools.

Example

Note: this is by no means complete documentation, but simply gives you an idea of what the API is like.

No recompilation is necessary to use these tools.

TC Malloc:

gcc [...] -ltcmalloc

Heap Checker:

gcc [...] -o myprogram -ltcmalloc HEAPCHECK=normal ./myprogram

Heap Profiler:

gcc [...] -o myprogram -ltcmalloc HEAPPROFILE=/tmp/netheap ./myprogram

Cpu Profiler:

gcc [...] -o myprogram -lprofiler CPUPROFILE=/tmp/profile ./myprogram

Sample Output

The heap profiler can pop up a window that displays information as a directed graph:

The cpu profiler can produce a weighted call graph:
