Out of curiosity, how large are the trees pushed there (in number of
files)? The code scales with the tree size, instead of delta size in
some places (that also affect push and pull). (see
http://article.gmane.org/gmane.comp.version-control.monotone.devel/16424 )

That code is CPU bound and has nothing to do with the database.
