Specifically, I would like to put Apache/PHP in a jail, but I might like to set up 2-3 different jails for different purposes. I've found several examples showing how to set the jails up. My questions involve system requirements. Assuming plenty of disk space, 1GB ram and a dual processor PIII 1.13Ghz system, how many jails can I run? Would I notice a significant performance hit if, for example, I run three jails?
