Just to close this off, when using Samba with ZFS it seems to be very important (if you have many files in a directory) to make it case sensitive as per: https://wiki.samba.org/index.php/Performance_tuning#Handling_Large_Director= ies. Everything is now roses and works as expected. Sorry ZFS that I accused you! ;) Thanks again! // Albert On Wed, Nov 25, 2015 at 2:23 PM, Albert Cervin <albert@acervin.com> wrote: > Hi again, > > I have conducted a few other experiments and concluded that ZFS is NOT > the culprit here and my suspicions now go to Samba instead which seems > to behave really badly under these conditions... > > Thanks for all the ZFS help though, much appreciated! > > Cheers, > Albert > > On Wed, Nov 25, 2015 at 1:16 PM, Gerrit K=C3=BChn <gerrit.kuehn@aei.mpg.d= e> wrote: >> On Wed, 25 Nov 2015 12:06:38 +0000 krad <kraduk@gmail.com> wrote about R= e: >> ZFS - poor performance with "large" directories: >> >> K> consumer SSDs are cheap enough now not to bother with usb drives I wo= uld >> K> imagine. >> >> Sure.
