I have a pair of machines that sync at 25-27 MB/s over gig-e, and the speed there is limited by two things: 1. the host CPU of one of the machines (Duron 750) 2. the speed of the rather old 5400 rpm ATA/100 drives. I hope to do some more tests soon with some slightly nicer hardware, I expect to do better. I should note that the BEST TCP benchmark I've got between the two existing machines is 35-40 MB/s so I don't think that drbd is that far off. -- Jon Nelson <jnelson-drbd at jamponi.net>
