Our LEA has just purchased SchoolsGuardian and we're having incredible performance problems. This is since it was installed in mid-January - a real pain.
Just wondering if this sounds right?
They're running it on a dual 3ghz machine with 2/4gb ram (sorry, i'll get some more accurate figures) for the whole LEA - 13 High schools average 800 kids on role I would think (Highest 950, lowest 300 ish) and 70 odd small primary schools.
Originally it was installed on a lower spec server.
Smoothwall have a hardware specification calculator:

how many concurrent computers?
I think 2000 is the estimated figure CyberNerd
the LEA were saying that the software didn't seem to be utilising the second CPU - and there was no way to configure it to.Quote:

Look for signs of a high load average, high swap usage etc. (IIRC there is a very basic load screen in the interface) other than that probably start looking at network problems - try pinging the server with 'ping -f' from a linux box - but get permission first! and look for any dropped packets - just small amount of dropped packets cause a major slowdown in network performance.
K thanks CN - i'll pass that on. I think the WAN connection is pretty solid - so I don't suspect thet.
also with top and multiprocessor systems. If you hit the '1' key you'll be given a per cpu readout instead of aggregated stats:
