Few (shorter :-)) questions

Hi, I'm interested is there something wrong with configuration (based on onstat results). First, it is Ultra Sparc computer, with 4 processors (1 processor has affinity set). onstat -g glo gives this output: >>Informix Dynamic Server Version 7.31.UC2 -- On-Line -- Up 15 days 21:33:37 -->>34016 Kbytes >> >>MT global info: >>sessions threads vps lngspins >>1 22 8 0 >> >> sched calls thread switches yield 0 yield n yield forever >>total: 98166674 13308567 82512806 3732982 75051 >>per sec: 24 12 0 9 0 >> >>Virtual processor summary: >> class vps usercpu syscpu total >> cpu 2 1835.88 585.96 2421.84 >> aio 1 0.04 0.08 0.12 >> shm 1 111.28 15.55 126.83 >> lio 1 0.01 0.07 0.08 >> pio 1 0.01 0.04 0.05 >> adm 1 0.01 0.08 0.09 >> msc 1 0.21 0.27 0.48 >> total 8 1947.44 602.05 2549.49 >> >>Individual virtual processors: >> vp pid class usercpu syscpu total >> 1 268 cpu 701.35 153.89 855.24 >> 2 269 adm 0.01 0.08 0.09 >> 3 270 cpu 1134.53 432.07 1566.60 >> 4 271 lio 0.01 0.07 0.08 >> 5 272 pio 0.01 0.04 0.05 >> 6 273 aio 0.04 0.08 0.12 >> 7 274 msc 0.21 0.27 0.48 >> 8 275 shm 111.28 15.55 126.83 >> tot 1947.44 602.05 2549.49 question: why cpuvp #3 has spent double time than cpuvp #1? onstat -g sch gives this output:>>VP Scheduler Statistics: >> vp pid class semops busy waits spins/wait >> 1 268 cpu 32 39 9447 >> 2 269 adm 0 0 0 >> 3 270 cpu 1103411 1103747 9999 >> 4 271 lio 2 0 0 >> 5 272 pio 2 0 0 >> 6 273 aio 421 0 0 >> 7 274 msc 2070 0 0 >> 8 275 shm 4 4 1000 question: why so much semops/busy waits for cpuvp #3? onstat -g iov gives this output: >>AIO I/O vps:>>class/vp s io/s totalops dskread dskwrite dskcopy wakeups io/wup errors >> kio 0 i 0.0 0 0 0 0 0 0.0 0 >> kio 1 i 0.0 14415 8498 5917 0 25440 0.6 0 >> kio 2 i 0.0 11597 9935 1662 0 21855 0.5 0 >> msc 0 i 0.0 2068 0 0 0 2069 1.0 0 >> aio 0 i 0.0 912 53 2 0 419 2.2 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 question: why there is kio #1 when it is working nothing?
