I kicked the first one. The load is really nothing though. It's only serving up static files, this takes next to nothing to do. The boxes are way over powered for the task. They hit bandwidth limits first, but I think we're well within that now too.

Example:
mas: load average: 0.07, 0.11, 0.08
masymas: load average: 0.00, 0.05, 0.27
masymasymas: load average: 0.00, 0.00, 0.00

Like literally nothing. They are serving up files too, as I can see in the logfiles.

Again, serving static files takes far less resources than serving up dynamic content. The first two boxes have 8 CPUs each. The last one is just a cheap Athlon XP. (The "mas" box is actually a virtual computer/kvm.)
