Comment 5 for bug 21790

I've attempted to identify culprits but have had no joy so far. If you can
assist with what I should be looking for in the bonnie output that would help
[Is it as simple as comparing the per second throughput counts?]

I'll also be trying to incrementally start services to identify where the
problem starts as soon as I'm back at a machine that exhibits this problem (My
laptop doesn't show this problem :( )

Have you any other ideas of how I can identify the problem?
