Ah, I didn't know there were these additional optimizations behind the scenes :)
dlmalloc has recently improved "bulk" (called "burst" in my paper) operations and those ideas can be used to improve adaptive pools, specially deallocation times (fast coalescing adjacent buffers before entering the complex deallocating code). Dlmalloc also implements its own spinlocks for some platforms, whereas my code uses critical section or pthread mutexes. I need to investigate if dlmalloc's internal spinlocks could be used in my pools. At least, to get a fair comparison ;-) Boost.Container's have also improved a bit in regards to extended allocators so figures need to be updated. When I realized that the new "plain" dlmalloc performed a bit faster than my pools, I didn't want to fall behind ;-) Ion
