LXC Device Mountpoint - High I/o delay

[voarsh]

I am syncing files to a USB HDD which is mounted on host and shared to an LXC.

The host/LXC HDD is not being used and the sync agent is syncing files to the /mnt/bidmounts/shared folder on the host.

I am experiencing extreme I/O wait delay, the sync agent is causing it, but the USB drive isn't that slow of a drive.

Doing the exact same thing on Windows is fine, I have no such performance issue.

Super strange, but I ran the exact same thing on a different node with USB 2 (other node was USB 3) and there's no I/O wait bottleneck...
