google-perftools是google所开发的系统优化的工具集，TCMalloc 是用于优化C++写的多线程应用，这个模块可以用来让MySQL在高并发下内存占用更加稳定。它依赖库libunwind。TcMalloc内存管理库，与标准glibc库malloc相比，TcMalloc在内存分配效率和速度上要高很多，可提升高并发情况下性能、降低系统负载、常用于Nginx优化等。Fast, multi-threaded malloc() and nifty performance analysis tools.
Perftools is a collection of a high-performance multi-threaded malloc() implementation, plus some pretty nifty performance analysis tools.
Perftools is distributed under the terms of the BSD License.
These tools are for use by developers so that they can create more robust applications. Especially of use to those developing multi-threaded applications in C++ with templates. Includes TCMalloc, heap-checker, heap-profiler and cpu-profiler.
