I have a very active website which is using a NoSql database (RavenDb). I don't have exact figures as i'm not quite sure how to extract this information (any help would be great!)
But looking in performance monitor at the '% Disk Read' counter on the disk my database is running from, it is regularly over 1000...which doesn't make sense if it's a perecentage???
My sites performance does decrease once these figures are this high, not so much that it's unusable but it should be better.
Am I looking at the right performance counters, what else can I look at to find out if my disk is under heavy load...and even better if i can find out why.
My disks are 2TB 7200 rpm disks (not ideal i know, but it's all I have available currently) 12GB Memory (uses about 80%) Dual Xeon processor
I understand that this question is a little vague, I need some help on getting the right details to you to help you answer this better, just let me know what will help.
