Hi All,

I experience a very slow performance on a Alpha 4100/Digital Unix 4.0D
hosting a Oracle DB.
Mem=1GB. CPU=1x 466, HSZ50-AX raid 1+0.

vmstat shows:

No pout
constantly pin
usertime 75
systemtime 25
idletime 0
free is constantly <= 256 (vm-page-free-target = 256).

Iostat shows a lot of disk I/O.

Is this system I/O bound ?

Thanks in advance.
Regards,
