Server lag question

[tcngs]

I am running a dual 2.8 xeon 64 bit with 800mhz frontside bus wil 2m L2 cache, I only have 1gb of ram in it right now. My question is some times if I am copying files or doing something on the server, the games servers will start to lag very badly. I check the cpu % and it is very low usualy between 10 and 15 %, what else can be causeing the lag if the cpu is running so low. Could it be the ram, not having enough in there? I am bumping it up to 2gb next week.

 

Also is there any good resource monitoring programs out there that any one would recomend? Thank you

IDE/SATA? Or SCSI?

[tcngs]

IDE 10,000 rpm

If the games are using the virtual RAM "eg. virtual memory/disk" due to too little RAM then disk operations may pose a problem.

[tcngs]

so more ram might help the problem, it is using DDR2 ECC, I eventualy will have 4gb in that box

[kalyse]

More RAM is always good.

FWIW: IDE disks do not support disconnected writes, which is a significant performance bottleneck when you are writing to the disk; only disconnected reads are supported.

[tcngs]

Can you elaborate more on disconnected writes, or point me to a site that has a good definition of it.

 

Also does any have any good tools for monitoring system resources, latency, etc. Thank you

Also you recommend SCSI or SATA

[ECF]

SCSI is recommended, but can be more costly than SATA.
