And from trshiv's link it looks like Hoard tcmalloc and ptmalloc are all roughly comparable for speed. Overall tt looks like.. all roughly comparable for speed. Overall tt looks like ptmalloc is optimized for taking as little room as possible Hoard is..
What is the best solution to replace a new memory allocator in an existing code? http://stackoverflow.com/questions/1519772/what-is-the-best-solution-to-replace-a-new-memory-allocator-in-an-existing-code with many threads. For example it seems that tcmalloc and ptmalloc have better performance. I have a C application that uses both.. many places. I thought replacing them with something like ptmalloc may improve its performance. But I wonder how does the new operator.. by using LD_PRELOAD LD_PRELOAD usr lib libtcmalloc.so ptmalloc seems to be similar but if you're on Linux you're likely already..
Scalable memory allocator experiences http://stackoverflow.com/questions/2514278/scalable-memory-allocator-experiences a few of scalable memory allocators namely nedmalloc and ptmalloc both built on top of dlmalloc as a replacement for default malloc..
Does dynamic memory allocation differ in C and C++ in popular implementations? http://stackoverflow.com/questions/7443782/does-dynamic-memory-allocation-differ-in-c-and-c-in-popular-implementations answers It looks like in GCC this is completely solved by ptmalloc and that MSVC also uses malloc at the core. Does anyone know.. 2.3 use a modified version of the allocator called ptmalloc which itself is a derivative of dlmalloc designed by Doug Lea..
