One might expect the load average to be well into the hundreds. This is something that has been in my mind for quite a while. Just exactly how is the load average on a machine calculated? It seems to very from OS to OS and I have never really been able to make much sense of it other than to tell if something really out of the ordinary is happening on a machine. (ie 6 hits at work and the load average shoots up I just ran into the daily backup, time to go home) > As for planned upgrades, we'll be going to Xeon/4xx in a month or so.
