Have you tried plugging the HOARD memory allocator into your program?
Yes. This provided a significant performance improvement, however it has some serious drawbacks a.. I experienced some crashes during testing b.. Commercial licensing is expensive c.. It 'hooks' system calls to malloc, a technique I consider dodgy. d.. It is a DLL, which I avoid since they result in endless configuration management nightmares.
Multicore aware programming is more than a simple issue, and certainly not solved just by an efficient allocator (although this doesn't hurt ;) ).
Gosh! Did I suggest anything like this? However, a well designed multithreaded program will slow down, rather than speed up, on a multi-processor machine when the standard memory allocator is used which took me, at least, completely by surprise and mystified me for several days. James
