Ok, understood - that answers my question and the one I just posted. So ... in 4.4 KVA space was, by default ... I forget ? So I guess my question has now morphed into: - if the machine is doing nothing but firewalling (so there are no other demands on KVM/KVA) how high can you set NMBCLUSTERS to before you start to get close to the default KVA in fbsd 4.4 ? (actually I think the default is the same in all 4.x, just the method of changing it is different) comments ? thanks!
