Hello,

We did not build the windows client ourselves. The ceph version we are 
connecting to is: 14.2.15

We followed the documentation here: 
https://docs.ceph.com/en/latest/install/windows-install/

  *   So we installed Dokan from here: 
https://github.com/dokan-dev/dokany/releases  (The issue occurs with version 
1.3.1.1000 and 1.5.0.3000)
  *   We then installed ceph for windows from here: 
https://cloudbase.it/ceph-for-windows/ which seems to be the same link you 
provided.

Would you like me to reinstall the ceph-for-windows and try that again?

Kind regards

Gabryel

Hi,



Did you build the Windows client yourself or is it a Suse or Cloudbase build? 
Which version is your Ceph cluster running, the one that you’re connecting to?



Early versions had a few known bugs which might behave like that (e.g. 
overflows or connection issues) but it shouldn’t be the case with recent 
versions. Could you try a recent msi from here?

Thanks,

Lucian

Hello,

I have tried with a native client under Linux and its performance is fine, also 
the performance under 1GB is fine on the windows machine.

Kind regards

Gabryel

Have you tries this with the native client under Linux ? It could be
just slow cephfs ?
