Why not? It's fast enough?
I think when even arrakis (040/40 with 64 MB) can deal happily with two
parallel builds without losing too much time, every other machine should be
able as well.
Granted, arrakis has 7 SCSI disks on two different hostadapters with 5
distributed swap partitions that are making swapping wonderful smooth, even
if some evil perl tasks use >590 MB of memory.
Sure, parallel builds don't speed up things, but they don't necessarily need
to slow down things either, when you do it right.
Well, if someone would ask me, I'd vote for removing this strange "this is a
buildd, please don't use it for manual builds"-motd policy. It does not make
any sense to me. When the buildd admin thinks, it will slow down the
machine, he could get some more machines to broaden the load. And I don't
think that f.e. mips has a hardware problem at all...
