IMPORTANT NOTE FOR 64-BIT USERS
-------------------------------
There are known issues with some perftools functionality on x86_64
systems. See 64-BIT ISSUES, below.
gperftools
----------
(originally 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.
OVERVIEW
---------
gperftools is a collection of a high-performance multi-threaded
malloc() implementation, plus some pretty nifty performance analysis
tools.
gperftools is distributed under the terms of the BSD License. Join our
mailing list at gpeftools@googlegroups.com for updates.
gperftools was original home for pprof program. But do note that
original pprof (which is still included with gerftools) is now
deprecated in favor of golang version at https://github.com/google/pprof
