[Gluster-users] Gluster 5.5 slower than 3.12.15

[Strahil Nikolov]

Hi Community,
I have the feeling that with gluster v5.5 I have poorer performance than it used to be on 3.12.15. Did you observe something like that?
I have a 3 node Hyperconverged Cluster (ovirt + glusterfs with replica 3 arbiter1 volumes) with NFS Ganesha and since I have upgraded to v5 - the issues came up.First it was 5.3 notorious experience and now with 5.5 - my sanlock is having problems and higher latency than it used to be. I have switched from NFS-Ganesha to pure FUSE , but the latency problems do not go away.
Of course , this is partially due to the consumer hardware, but as the hardware has not changed I was hoping that the performance will remain as is.
So, do you expect 5.5 to perform less than 3.12 ?
