You really are not supposed to install Ubuntu to an external drive and plug it in to two different PC's. The problem lies in Ubuntu constantly reconfiguring itself whenever it's switched computers. So the lag comes down to that. Misconfigurations and drivers being tossed about. It's just Ubuntu prefers the school PC to your home's due to simpler hardware most likely. If you need a portable version of Ubuntu, make a bootable Ubuntu USB with Persistance on a 4GB or larger USB thumbdrive. That way Ubuntu can be more flexible when it comes loading drivers as it dosen't save those configurations, usually.
