I cannot find kio or kaio in the release notes for 9.40 on Solaris, but my understanding is that KAIO is always on in Solaris unless you work to stop it? If so, why do I only see 2 kaio listed when I have 3 cpu vp's? I thought it was automatically 1 kaio thread per CPUVP: VP Scheduler Statistics: vp pid class semops busy waits spins/wait 1 2408 cpu 33 72 7009 2 2409 adm 0 0 0 3 2410 cpu 42 48 9948 4 2411 cpu 3 3 10001 5 2412 lio 2 0 0 6 2413 pio 2 0 0 7 2414 aio 103 0 0 8 2415 msc 5 0 0 9 2416 aio 2 0 0 10 2417 tli 2 2 1000 AIO I/O vps: class/vp s io/s totalops dskread dskwrite dskcopy wakeups io/wup errors kio 0 i 0.3 96 81 15 0 191 0.5 0 kio 1 i 0.1 30 28 2 0 59 0.5 0 msc 0 i 0.0 3 0 0 0 4 0.8 0 aio 0 i 0.3 100 15 6 0 101 1.0 0 aio 1 i 0.0 0 0 0 0 1 0.0 0 pio 0 i 0.0 0 0 0 0 1 0.0 0 lio 0 i 0.0 0 0 0 0 1 0.0 0 Is there something new I need to RTFM for 9.40? (what else am I going to ask as I proceed with 9.40?-)

I think kaio thread number 3 will be added on demand. I saw that behaviour under 7.31.FC6 AIX 5. Just run a couple of sqls or client apps and check again.
