Hi Ketil,
I have not tested the creation/deletion but the read/write performance
was much better then the link you posted. Using CTDB setup based on
Robert's presentation, we were getting 800 MB/s write performance for
queue depth =1 and 2.2 GB/s queue depth= 32 from a single CTDB/Samba
gateway. For the QD=32 test we used 2 Windows clients to the same
gateway (to avoid limitation from the Windows side). Tests were done
using Microsoft diskspd tool at 4M blocks with cache off. Gateway had
2x40 G nics : one for Windows network the other for CephFS client, each
was doing 20 Gbps (50% utilization) cpu was 24 cores running at 85%
utilization taken by the smbd process. We used Ubuntu 16.04 CTDB/Samba
with a SUSE SLE15 kernel for kernel client. Ceph was Luminous 12.2.7.

Robert,
Thanks, this is really interesting. Do you also have any details on
how a solution like this performs? I've been reading a thread about
samba/cephfs performance, and the stats aren't great - especially when
creating/deleting many files - but being a rookie, I'm not 100% clear
on the hardware differences being benchmarked in the mentioned test.

Hi Ketil,
use Samba/CIFS with multiple gateway machines clustered with CTDB.
CephFS can be mounted with Posix ACL support.
Slides from my last Ceph day talk are available here:
