[Boost-users] pool allocator performance with multiple threads

Does anyone know if the fast_pool_allocator is supposed to work in a multithreaded environment? I know that it is "thread-safe," but I'm getting some really discouraging test results from it. Namely, using fast_pool_allocator is consistently performing about 10 times SLOWER for me than new/delete whenever multiple threads are involved. I've tested and come up with the same results on three different platforms: Mac, Linux and Windows (MSVC). I get the impression that I just need to roll my own allocator if I'm using more than one thread, but I'm hoping that this is not the case. If it helps, I can put together and post some source code that demonstrates these results. Thanks, -Mike
