I was reading through the thread started by Aliboy66 on low virtual memory. I read Nikas' reply and decided to check out my own PC and found that it was set to 1563MB and as I have 1GB of RAM was happy as this was what Nikas recommended.

I then followed Usasma's instructions on checking the disc reads. The majority of them were from the small 100's to the small 1000's but three in particular stood out.

(1) lsass.exe-----System-------Mem/Us = 1,164k-------I/O Reads = 6,060,204.
(2) csrss.exe----System-------Mem/Us = 3,128--------I/O Reads = 776,169.
(3) cmdagent-----System-------Mem/Us = 5,824-------I/O Reads = 3,052,505.

cmdagent is to do with my Comodo Firewall Pro. I Googled the other two and found that they are both genuine Windows files but would like an opinion on whether the disc reads are too high and what can I do about it.

Again thanks in advance,
Bluesjunior.

The IO Reads column is used to see if there's excessive disk reads going on. Excessive is a relative term, and is only of use when applied to a particular set of circumstances that cause one to believe there might be an issue with a misbehaving program (rather than another cause that might have been discovered earlier in the troubleshooting process).

That being said, 6 million and 3 million reads is a bit excessive for all but a few programs (mostly antispyware and antivirus). The most common cause these days is a corrupt Windows Update. I'd suggest trying to disable Windows Update to see if this fixes the issue.

Thanks for the reply Usasma,

Yes, disable it to see if that's what's causing the excessive IO Reads (this in only a temporary measure - re-enable it after you're done testing). If that's it, then there's fixes available for it.
