I think that at this point that would be complicated enough to simply add compression instead. lzo would probably be a great fit for this: http://www.oberhumer.com/opensource/lzo/ but I suspect that this is beyond what the developers want. They would probably tell you to use openvpn. Has anyone ever tried openvpn with drbd without encryption enabled to see if it can speed things up (it can use lzo)? -Martin __________________________________________________ Do You Yahoo!?
