[sheepdog-users] sync speed

[Valerio Pachera]

After the crash of today, my cluster is still syncing data.
>From atop command I can see that network and disks I/O activity is not so
intensive:

eth0 is generating 150Mbit/s pf traffic.
But it's a gigabit , so it could go much faster.
Disk is busy 55%.

What do you think about?
Is sheepdog limiting the sync speed to leave I/O for guests?
Does sync have any relation with cache?
