Bug#488728: knode: very high number of cpu wakeups
Package: knode
Version: 4:3.5.9-3
Severity: normal
powertop shows a very high number (around 1000/s) of cpu wakeups for
knode, which is a very bad thing i.e. for laptop use.
A little digging in the source reveals that the protocol client does
select() calls with a timeout of 1000 usec. Changing the relevant
timeouts to 1 s resolves the problem (I use this approach since about
three months now, no bad side effects as far as I can see.)
