Hi! I've tried libumem as Stephen suggested, but it is slower than the regular system malloc. This (libumem) is really geared toward the integration with the mdb (solaris modular debugger) for memory debugging and analysis.
But, I've found: http://www.nedprod.com/programs/portable/nedmalloc/index.html and this looks more promising. I have run its (supplied) test and it seems that, at least speedwise, the code is faster than native OS malloc. I will now try to make it working on all platforms that we use (admitently, it will not run correctly if you do not set -DNDEBUG to silence some assertions; this is of course not right and I have to see why/what). Anyways.... perhaps a thing to try out... If you get any breath-taking news with the above, share it here. On my PPC powerbook (1.5GHZ PPC, 512 MB memory) I get improvements over the built-in allocator of a factor of 3 (3 times better) with far less system overehad. I cannot say nothing about the fragmentation; this has yet to be tested. Cheers Zoran
