Alright...

I'll give you a nice working PS/2 9595 server, in a straight up trade
for the server you have. Deal? <g>

I'll even pay shipping.

It feels like it must be in the drive subsystem, if the rest of the hardware and
the software config is so identical.

Why RAID 0 on the two 4.5G's, which I assume are system drives? Can they be set
up as RAID 1? 

Are all the drives on the same SCSI Channel? If so, can they be seperated onto
two channels? In general, I'd look closely at the SCSI config.

Hi

why the scsi is your main suspect ? I said that the problem I experiened was
network performence oriented.

I have a feeling your are right , but why the scsi ?

Share what you know. Learn what you don't.

What server do you want , why ?

It was a joke;->
In market value, his server is worth MUCH more than my PS/2 9595. So, I
would trade him, then sell the server I get from him, and get ?50? full
9595 systems... I'd be in MAD Heaven...

You've got a *lot* more going on there than just "network performance". You're
getting requests, processing them, pulling bits off of those drives, then
spitting them out to the network. It's hardly a simple "network performance"
problem. It's a *server* performance problem, and from what little I know, the
disk subsystem felt like the place to look first.

You can also start using performance monitor to see what subsystems are the
limiting factor. This takes time and some insight to figure out just what to
monitor.
