I don't have to worry about any nazi-admins on the dev servers - if anyone is a nazi-admin around here it's me
I built a few little batch files based on a few things in this thread and just started up 4 clients running them on our two test servers (each a dual 2.8) If things go well I'll start spreading it to more boxes. By the weekend if you stay at 34 machines Joe I might be able to match your output (during non-business hours).
And while I'm thinking about it - has anyone tested whether it's faster to run one instance or two on a HT'd CPU?
