Hello Amar,
thank you for the advice. We already use nl-cache option and a bunch of other settings. At the moment we try the samba-vfs-glusterfs plugin to access a gluster volume via samba. The performance increase now.
Additionally we are looking for some performance measurements to compare with. Maybe someone in the community also does performance tests. Does Redhat has some official reference measurement?

For Samba usecase, please make sure you have nl-cache (ie, 'negative-lookup cache') enabled. We have seen some improvements from this value.-AmarOn Tue, Dec 18, 2018 at 8:23 PM David Spisla <spisla80@xxxxxxxxx> wrote:_______________________________________________Dear Gluster Community,it is a known fact that Samba+Gluster has a bad smallfile performance. We now have some test measurements created by this setup: 2-Node-Cluster on real hardware with Replica-2 Volume (just one subvolume), Gluster v.4.1.6, Samba v4.7. Samba writes to Gluster via FUSE. Files created by fio. We used a Windows System as Client which is in the same network like the servers.The measurements are as follows. In each test case 400 files were written:64KiB_x_400 files 1MiB_x_400 files 10MiB_x_400 files1 Thread 0,77 MiB/s 8,05 MiB/s 72,67 MiB/s4 Threads 0,86 MiB/s 8,92 MiB/s 90,38 MiB/s8 Threads 0,87 MiB/s 8,92 MiB/s 94,75 MiB/sDoes anyone have measurements that are in a similar range or are significantly different?
We do not know which values can still be considered "normal" and which are not.
We also know that there are options to improve performance. But first of all we are interested
in whether there are reference values.
