   > But then again, I work in a severely memory constrained environment Then likely you're dealing with a single-threaded application where dlmalloc will work just fine. No multi-threaded contention for allocation/deallocation.

   Custom allocators have the disadvantage of not knowing how the rest of the heap is managed. They are at a disadvantage to a modern well designed memory allocator like hoard or jemalloc. Feel free to examine the many papers put out by Emery

   My use of jemalloc in multithreaded servers shows the opposite to be true. Memory use is a little higher than the single mutex dlmalloc, but you'd expect this with a modern high performance thread aware malloc implementation. You think

   > One major limitation of malloc (and even the best implementations like jemalloc and dlmalloc) is that they try to use a single allocator for each data structure. This is a mistake: A huge performance gain can be had by using a separate
