more data:
- irq21 seems to always carry about half of the number of interrupts
atapci1 is carrying.
- over large periods, the % busy of ad6 is at 100%, servicing maybe 350
or even 800 requests/sec. I/O speed then is around 3-10 MB/sec. this
is with 1.10 and SMP. I'll try compiling a old-ata kernel now.
Okay, old ata kernel does not help. I'd even be inclined to say "looks even
worse", but that might be subjective. We definitely need an I/O scheduler and a low
level disk scheduler.
cheers
