I'm starting the process of moving my school's Moodle installation from a hosting company to a dedicated server. I have some experience with small Moodle installations. This is not going to be a huge setup, but it will be larger than what I've done before and I'm trying to estimate our hardware needs.
Unfortunately the only usage statistic I have from our hosting company is log entries / 5 minutes. They are reporting a peak value of ~150 entries / 5 minutes. I'm trying to get from this number to an estimate of our RAM requirements, but I don't really know what it represents in terms of concurrent users / php requests per second. Can anyone offer insight? I know this is not an exact science... Thanks in advance!
