</div></div>This push test isn't even remotely fair - you're pushing to a normal git repository on a local spinning disk, but to hg-on-bigtable which is *known* to be almost an order of magnitude slower than stock hg. Consider retrying your benchmark to a hosting provider with a more orthodox setup? Preferably push both repositories to the same machine so you can have known-similar hardware?</blockquote>
