[Gluster-users] Slow performance on samba with small files

[Дмитрий Глушенок]

Hi,

There is a number of tweaks/hacks to make it better, but IMHO overall performance with small files is still unacceptable for such folders with thousands of entries.

If your shares are not too large to be placed on single filesystem and you still want to use Gluster - it is possible to run VM on top of Gluster. Inside that VM you can create ZFS/NTFS to be shared.
