[distcc] where does preprocessing take place

If you say so ;)

I would happily benchmark any patch you'd send to me.

Is this on purpose, because doing otherwise isn't possible? Looks quite
clear to me that feeding the distant host with preprocessed data as we
generate it, rather than afterwards, would represent a substantial gain.
Again, I wouldn't know how to change the code to do this, if only this
is possible at all, but would benchmark any test patch you would come up
with.

Thanks,
