Somewhat related (or not) to using a different memory allocator than MSVCRT, Patch to make string-append on Win32 100 times faster. This change makes Perl grow/realloc strings exponentially geometrically instead of by a fixed amount and hence showed a speedup at least for Windows, by avoiding calls to realloc(). On Linux, at least with certain allocators, a slowdown was found. For BSD, Perl already uses its own allocator.
