I've worked with several projects where a TCMalloc based allocator (threaded) was used to great success. A simple switch to DLMalloc (non-threaded) can also provide a significant performance boost. Moderate usage of STL can do nasty, nasty things to memory performance. In one case a game I worked on ran at 5-10fps and a simple, fast change to DLMalloc instantly took perf to 60fps.

It's worth noting that at least on some platforms the system malloc is dlmalloc (presuming that DL is Doug Lea).

  Which platforms?

    glibc's malloc has long been based on Doug Lea's malloc.

+1 for TCMalloc. We used TCMalloc at Opera Community[0], and they still might be using it there for all I know ... it greatly improved performance on our MySQL servers! [0]: http://my.opera.com/ http://my.opera.com/

  Aren't you using Percona build ?

    Not when I worked there, but it's a few years ago. Don't know what they use now.
