[Piuparts-devel] Multiple/remote piuparts slaves

[Dave Steele]

I'm running piuparts-server on VM on a quad-core 2.2GHz Phenom. The VM has
a single CPU, and 2G ram. It is backed by a 20Gb partition on a utility 1Tb
drive. An external caching proxy is used to access the mirror.

It looks like it runs at a rate that would complete sid testing in about 2
weeks. Packages tick by at about one per minute. Processor utilization is
routinely 100%.

I added a second, identical VM, backed by the same drive, to run an
additional slave. The testing rate doubled. This implementation, at least,
is entirely CPU bound.

There appears to be a race condition on the 'reserve' command. The same
packages are sometimes tested by both slaves. The last slave to copy these
log files back crashes piuparts-master repeatedly in the 'send' command,
from Exceptions in packagesdb.py.

Is anyone else running multiple slaves? If so, what performance/issues do
you see?
