I have  a very strange situation here. There was a hosting box with 5
Everything is 6.4
It was running twe driver with RAID 5.

Then i had a crash and had to reinstall the system.

So, i have installed FREEBSD 6.8, cvsed the latest, rebuilt everything
and then
just copied jails from the prev installation. So, the host system is 6.8
and the jails are 6.4.
Also, raid is MIRROR now, not RAID5.

If you had to reinstall, you may have missed a boot loader configuration. I would investigate how your raid5 went to MIRROR, that would certainly account for the high system time if the OS and raid card think differently about the raid system used. How you'd go about this, is for someone else to answer. I personally would compare daily runs and dmesg's saved from before reinstall with current installation.
I am sure this is not the case because the new raid was simply recreated manually using 3ware bios and
then freebsd installed and then old data copied from backup.

BTW, here are the interrupts:
interrupt                          total       rate
irq14: ata0                           47          0

Total                        10616678935       8145

And here is vmstat -i output from another box running 7.1

interrupt                          total       rate
irq1: atkbd0                        1478          0
irq6: fdc0                             1          0
irq14: ata0                           69          0
irq17: pcm0 twe0                37631996         27

irq22: fxp1                        86882          0

cpu1: timer                    557037363        399
Total                         1212501275        870

So, this 6.4 gets 9 times more interrupts (mostly timer).
Is is okay?
