[Casper] Using Casper Distribution Points

[Brad Rellinger]

Not sure if this helps or not.
We just put in a new Xserve for the JSS. 2 x 2.93 Quad-Core CPU's. 24GB RAM.
Connected via Gigabit (Link Aggregation between 2 Gigabit ports).

Yesterday we were imaging 30 Intel iMacs with about a 60GB image.  The
throughput hit about 120MB/s with the average being 80MB/s.  During that
time CPU utilization sat around 10% (out of 100%).

Point being that, in terms of imaging (with unicast), you are most likely
going to max out the network throughput before you max out the CPU or RAM.

I'm not sure how it will preform during the school year with all the
policies, check-ins, and recons happening. (We have around 2500 clients)
