Thanks for the responses here folks. Our VM for our LTSP server is currently 8GB or RAM and I arbitrarily set it to have a 4-core CPU. Steve, how many CPUs does your VM use and is increasing this number really effective or just more overhead in your (or anyone's) experience?
I'm seeing slowdowns mostly with video play back by monitoring network bandwidth output from the virtual NIC. I also see some performance slowdowns if a user fires up RStudio - but I think that depends on what they're doing with RStudion (we are a Statistics department - and stats research should be done NOT on the LTSP server anyways). I'm wondering if network bandwidth is by biggest hurdle - what could I possibly do to keep the LTSP server as a VM but keep that outgoing network activity manageable through a fat pipe. I should look closer at the virtual NIC specs as the actual VM host machine has dual 10 GB NICs on it - but of course shared with many other VMs on the host.

This is in a multiple school environment, using computer labs. We automate an off-hours LTSP server reboot 2x a month to help clean things up and maybe only 3x a year do we need to do a server reboot manually. Sometimes we'll temporarily assign up to 4 CPUs when doing an image rebuild, as we've read somewhere that aids in the rebuild time (and I've seen that firsthand).
