Is there a command that I can run that provide me the syscall/sec value,
that I could use in a script? I know vmstat reports it, but is there an
easier way the having to parse the output? a perl module maybe, that
already does it?
Thanks ...

Details on the array's performance, I think. Software RAID5 will
definitely have poor write performance (logging disks solve that
problem but vinum doesn't do that), but should have excellent read

The more I'm looking at this, the less I can believe my 'issue' is with
vinum ... based on one of my other machines, it just doesn't *feel* right
I have two servers that are fairly similar in config ... both running
vinum RAID5 over 4 disks ... one is the Dual-Xeon that I'm finding

Of course a software RAID5 is slower than a plain file system on a
disk.
