[distcc] Slower with distcc?

[Christer Solskogen]

Hi!

I have two machine, which are both pretty fast (Intel i7 3930k and i7 3770), but
when I for instance compile the linux kernel its slower with distcc than without.

linux kernel (defconfig on amd64)
without distcc
real    1m56.221s
user    13m40.459s
sys     1m9.895s

with distcc
real    2m7.527s
user    4m59.834s
sys     0m44.977s

Both machines are on the same gigabit network.
