Hi I am currently testing gluster 3.9 replicated/distrbuted on centos 7.3 with samba/ctdb. I have been able to get it all up and running, but writing small files is really slow.
If I copy large files from gluster backed samba I get almost wire speed (We only have 1Gb at the moment). I get around half that speed if I copy large files to the gluster backed samba system, which I am guessing is due to it being replicated (This is acceptable). Small file write performance seems really poor for us though: As an example I have an eclipse IDE workspace folder that is 6MB in size that has around 6000 files in it. A lot of these files are <1k in size. If I copy this up to gluster backed samba it takes almost one hour to get there. With our basic samba deployment it only takes about 5 minutes. Both systems reside on the same disks/SAN. I was hoping that we would be able to move away from using a proprietary SAN to house our network shares and use gluster instead. Does anyone have any suggestions of anything I could tweak to make it better ? Many Thanks *Gary Lloyd* ________________________________________________ I.T.
