One thing about it, the speed is likely what its going to be. Whether it is the encryption or whatever, it is what it is. It did improve a little with the 1GB network card but not a whole lot. >> Mostly, I need a better CPU. If I encrypt anyway. > Did you ever tell us the exact CPU you have in there?

It lists some extensions but I don't see any that are related to encryption. No AES or whatever for sure. Unless I missed it. I used the command cpuid to get this info on BSD. My main rig has a AMD FX-8350 Eight-Core Processor and 32GBs of memory. I'm thinking about a new rig eventually. Rig is getting a little age on it. ;-) Dale :-) :-)
