Hi guys i've got a 3 node ceph enabled cluster where I store templates on cephfs.

When I try to download new LXC templates through the gui the downloads take ages.

I've nailed this down to poor wget performance on cephfs.

If I download the LXC using wget inside the template folder the download speed is in the order of 50 kbps.

However, if i wget outside the cephfs folder, for instance the root home folder, I get 60mbps

To thicken the plot, if i Use curl to download the same template inside the cephfs folder I also 60mbps.

Do any of you know why wget performs so badly on cephfs, and possibly how to fix this?
