So no profiling...

The problem is that you can't contribute anything that is related to
that class that you linked before. See
http://mono-project.com/Contributing under 'Important Rules'.

It's HttpResponseStream.cs all the *Bucket classes that then use an
IntPtrStream.

I still don't think that allocating MemoryStream (256 bytes by default)
is hurting that bad. A wild guess is that the BufferedStream wrapping
the NetworkStream is allocating much more memory (4kB by default). But
if the code is rewritten following what xsp does, this should not be a
problem any more.
