If someone is following this, they probably want the possible explanation and not the knowledge of you having the possible explanation. So you are saying if you do eg. a core installation (without gui) of 2016/2019 disable all services. The fio test results are signficantly different to eg. a centos 7 vm doing the same fio test? Are you sure this is not related to other processes writing to disk? -----Original Message----- From: Frank Schilder [mailto:fr...@dtu.dk] Sent: maandag 13 juli 2020 9:28 To: ceph-users@ceph.io Subject: [ceph-users] Re: Poor Windows performance on ceph RBD. To anyone who is following this thread, we found a possible explanation for (some of) our observations. We are running Windows servers version 2016 and 2019 as storage servers exporting data on an rbd image/disk. We recently found that Windows server 2016 runs fine. It is still not as fast as Linux + SAMBA share on an rbd image (ca. 50%), but runs with a reasonable sustained bandwidth. With Windows server 2019, however, we observe near-complete stall of file transfers and time-outs using standard copy tools (robocopy). We don't have an explanation yet and are downgrading Windows servers where possible. If anyone has a hint what we can do, please let us know.
