which version of irqbalance is this?


$ dpkg -l | grep -i irqbalance
ii irqbalance 0.55-2.4 Daemon to balance interrupts for SMP systems

Kyle stated:
If there is only one cache domain, ie: one physical cpu socket with two
cores sharing a cache, then irqbalance will return after the initial
balance since it would be pointless to continue running. (It forces
itself into oneshot mode.)

The CPU = E6700 so yep, so if there is one physical socket with 4 cores it
keeps? For it to keep and not oneshot you need > 2 cores?
