A quick fix is to add more free list entries, and in particular an
entry for very small blocks since your test case seems to create a lot

Thank you Alexandre, this patch speeds up HomeSite a lot. It's still not
as fast as in Windows, but it's OK.

Thanks for the link!
I don't know, would it be technically possible to back heap allocation
by one of these alternative memory allocators mentioned on that page? If
so, you could get a "free" performance advantage over native by simply
using a better allocator (for some programs, at least).
A problem that Wine will be facing is the need to support the HeapWalk
function. Applications should not use it, because the speed of the heap
implementation degrades (mentioned on MSDN), but maybe there are
applications that need it.
