There's also a <a href="http://code.google.com/p/microallocator/" rel="nofollow">micro-allocator</a> especially tuned for lots of tiny allocations (which are typical for the STL), but I didn't use it yet. Never tried STLport, I often hear that it's supposed to be faster than the Dinkumware STL, but I'd really like to hear of some "success stories" :) Yeah, another very nice memory allocator is nedmalloc, the latest versions are able to override the standard allocator.

I simply used a custom allocator and doug leas dlmalloc (but which I think is not threadsafe?), this speeded things up considerably on win32, http://epsilon-delta.net/articles/vc7_stl.html#use-a-custom-allocator. Initially I wrote a simple hashmap with c++ standard library, and my P3500 running debian (g++4.3, libstdc++) would outperform my quad core 4gb win xp machine (vc7.1 + standard library) :-/ whooops. stlport on win32 is also generally faster.

why are you using an ubuntu based distro to compare speed? you should be using a less bloated distro such as arch gentoo or slack

Since the source code is available for a lot of libraries on Linux and not so much on Windows, I think that is the reason he chose Linux. Not due to the lack of good IDEs on Windows. @Bill
