I tried messing around with this with Amazon EC2. The problem was
that due to latency I only really saw the benefit for VERY high levels
of parallelization (think -j25+).. However, make isn't actually
"distcc-aware" so it just runs 25 jobs of anything in parallel. So,
anytime a makefile launched a ton of java or python jobs the host
ground to a halt as it wasn't distributed and it was way more than the
host could handle (especially java - which swapped like there was no
tomorrow).
If somebody were to do a distcc-ng for a large cluster one of the
problems to solve would be having it not run jobs in parallel if it
couldn't actually distribute them.
