Hello,
I have initialised my syncing rate to ~10MB/s
drbdsetup /dev/drbd/2 show
Lower device: 08:13 (/dev/sda13)
Meta device: internal
...
Syncer options:
rate = 10240 KB/sec
group = 1
al-extents = 257
But when i'm editing /proc/drbd file, i see a syncing rate of ~3MB/s
(average).

I increased sndbuf-size to 512KB and MTU to 9500 but without any
results.......
But if i launch a software (here bonnie++) that do some writes on Primary
then
syncing speed increases ~ 8MB/s ??
(i disconnect/connect drbd2 for update sync average)
