...re going to > do scaling with the Linux client. Some preliminary numbers on this. I've enabled multi-conn for both the file and memory plugins, and I'm using fio with 8 threads to test this against the Linux kernel client. Without multi-conn: memory: read: IOPS=52.8k, BW=206MiB/s (216MB/s)(24.2GiB/120002msec) write: IOPS=52.8k, BW=206MiB/s (216MB/s)(24.2GiB/120002msec) file: read: IOPS=48.3k, BW=189MiB/s (198MB/s)(22.1GiB/120001msec) write: IOPS=48.3k, BW=189MiB/s (198MB/s)(22.1GiB/120001msec) With multi-conn (-C 8): memory: read: IOPS=103k, BW=401MiB/s (420MB/s)(46.0...

Dear gluster experts, We have encountered a severe performance issue related to quota feature of gluster. My underlying fs is lvm with xfs format. The problem is if quota is enabled the io performance is about 26MB/s but with quota disabled the io performance is 216MB/s. Any one known what's the problem? BTW I have reproduce it several times and it is related to quota indeed. Here's the test: __________________quota enabled________________________________________ -sh-4.1$ sudo gluster volume info test_replica2_dis4 Volume Name: test_replica2_dis4 Typ...
