Hi Lars -
I had tried 1M for the sndbuff size earlier, but per your suggestion I
tried default and also 64K
both were about: 5,028 (4,688) K/sec
drbdsetup /dev/drbd0 show
Lower device: 08:33 (sdc1)
Meta device: 08:34 (sdc2)
Meta index: 0
on-io-error = detach
Local address: 10.100.100.1:7789
Remote address: 10.100.100.2:7789
Wire protocol: C
timeout = 6.0 sec (default)
connect-int = 10 sec (default)
ping-int = 10 sec (default)
max-epoch-size = 2048 (default)
max-buffers = 2048 (default)
sndbuf-size = 131070 (default)
ko-count = 0 (default)
rate = 102400 KB/sec
group = 1
al-extents = 127 (default)
I couldn't really tell a difference between those two or 1M... I
haven't tried jumbo frames so that might help, what do you think?
Thanks again for all your help!
