"great" perftools (formerly google-perftools)

Edit Package gperftools

The gperftools package contains some utilities to improve and analyze the performance of C++ programs. This includes an optimized thread-caching malloc() and cpu and heap profiling utilities.

Formerly the google-perftools package.

  * Bryan Chan has contributed s390x support
  * stacktrace capturing via libgcc's _Unwind_Backtrace was implemented
    (for architectures with missing or broken libunwind).
  * "emergency malloc" was implemented. Which unbreaks recursive calls
    to malloc/free from stacktrace capturing functions (such us glib'c
    backtrace() or libunwind on arm). It is enabled by
    --enable-emergency-malloc configure flag or by default on arm when
    --enable-stacktrace-via-backtrace is given. It is another fix for a
    number common issues people had on platforms with missing or broken
    libunwind.
  * C++14 sized-deallocation is now supported (on gcc 5 and recent
    clangs). It is off by default and can be enabled at configure time
    via --enable-sized-delete. On GNU/Linux it can also be enabled at
    run-time by either TCMALLOC_ENABLE_SIZED_DELETE environment variable
    or by defining tcmalloc_sized_delete_enabled function which should
    return 1 to enable it.
  * we've lowered default value of transfer batch size to 512. Previous
    value (bumped up in 2.1) was too high and caused performance
    regression for some users. 512 should still give us performance
    boost for workloads that need higher transfer batch size while not
    penalizing other workloads too much.
  * Brian Silverman's patch finally stopped arming profiling timer
    unless profiling is started.
  * Andrew Morrow has contributed support for obtaining cache size of the
    current thread and softer idling (for use in MongoDB).
  * we've implemented few minor performance improvements, particularly
    on malloc fast-path.
  * issue that caused spurious profiler_unittest.sh failures was fixed.
