Please help me make more meaningful graphs for my boss! Our department runs computer labs on campus, and being the end of the school year we're looking at utilization rates. I can give him: number of users served per hour; number of machines used per hour; and average session time per hour. What he also wants is some sort of utilization, or fill factor graph. But none of us can really figure out what formula to use. [more inside]

I have been noticing a problem with my work laptop which is running XP SP2. If left up and running all night, then on most mornings i find out it is running very sluggishly with 100% CPU utilization (from the graph). First I thought may be it is firefox with its large number of open tabs. But I am not so sure anymore. killing firefox does not help. Also when I look at the CPU column in task manager i cant quite figure out what is causing that 100% utilization. None of high numbers on the CPU column look suspect. Obviously I am missing something here. One thing I am not 100% sure, and there may be something to it, is that I may have seen this problem more often when I am using wifi instead of wired LAN at home. But I need to verify this. After this happens I usually have to reboot the machine after bringing it back to work. I am able to suspend the machine and bring it to work and plug it into the work LAN. But unless I reboot it it really runs slow. Just logging out does not help. [more inside]
