I just wanted to make sure that there are no timeouts for drbd due to network latency. The values are rather conservative, obviously.

The man page says to increase max-buffers for high performance. 11 Mbit WLAN is rather low-performance so I figured that a small max-buffers value won't hurt. I'd call the man page a bit misleading here! ;-)

Have set it to 2048 now and will retry.

Thanks for your hints.
