[Gluster-users] Very slow writes through Samba mount to Gluster with crypt on

[Whit Blauvelt]

Hi,

We have Glusterfs 3.8.7 with the crypt translator enabled on Ubuntu 16.04
with Samba 4.3.11. With or without the VFS module enabled, files dropped
through an SMB mount from a Windows workstation are painfully slow -- a
minute for a file that transfers in several seconds through a
similarly-configured Samba to a plain filesystem. 

Glusterfs mounts accept file transfers far more quickly. But with Samba, the
response of staff has been "We can't use this." There's no speed advantage
in this use for the VFS module either, surprisingly. 

Is there some known formula for getting performance out of this stack, or is
Samba with Glusterfs with encryption-at-rest just not that workable a
proposition for now?

Thanks,
Whit
