Hello Get this on first write made ( by deliver sending mail to inform of the restart of services ) Home partition (the one receiving the mail) is based on ocfs2 created from drbd block device in primary/primary mode These drbd devices are based on lvm. system is running linux-3.5.0, identical symptom with linux 3.3 and 3.2 but working with linux 3.0 kernel reproduced on two machines ( so

...combining them with the change of SO_SNDBUF to 1500 suddenly improved the speeds up to about 6 Mb/s! It appeared that with these registry changes, setting SO_SNDBUF to any value in the range 1404 - 1872 gives the same speed of 6.0 - 6.4 Mb/s, while changing it even one byte lower / higher immmediately drops the speed to less than 1Mb/s. However, while this is partial solution I could live with, this is still not the normal speed, so I still would like to find the way to bring it to normal values. It seems that I'm not the only one who have similar problems: see BUGs 2117 and 3706...
