I'm using SUN x4600 with 64GB ram and 2 SAS 146GB 10krpm with Solaris 10
One told me, that the system seems to be slow, so I did a iostat -xtc 5 2
which showed for a long period of time only 4-6000 kw/s and 100%b
dbserver:~ # iostat -xtc 5 200 extended device statistics tty cpu
device r/s w/s kr/s kw/s wait actv svc_t %w %b tin tout us sy wt id
sd0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0 0 0 6 1 1 0 98
sd1 1.2 76.3 154.3 4266.3 1.3 5.4 86.1 1 100
sd2 1.0 0.9 14.7 2.6 0.0 0.0 14.5 0 1
This looks slow to me, too. Are there more tools to discover the reason or where might I solve the root cause?
Thanks Stefan
