Wouldn't it make sense to not run tests on the machine where the results
are generated?

Are you using --fast for zipping the files? This can make a real
difference, both in terms of speed and - unfortunately - also in terms of
size. But I think it would be worth a try if you don't use it already.

The most obvious would be not to use XSL, but this has been discussed in
the past already, IIRC.
