Well, for all my other servers, I standardized on ext4. Since a vFirewall have to perform lots of packet-juggling, I'd rather dedicate the CPU time to the kernel rather than the HD I/O. Of course, a vFirewall needs to be updated every now and then, but everytime an update is called for, it should not overly tax the CPU and degrade the netfilter framework.
