This is a good one.
BTW, what would be such specialized apps on BQ?
Comparing to old RaQs, BQ has slight disatvantage in performance, IMHO.
I am trying to tune once everything possible to a reasonable extent.
BQ usually has heavy load on mail, which alone provides enough disk I/O.
I thought that this trick might reduce this from apache side.
And I definitely want /tmp and /var/run be tmpfs, with noatime set!
