Hi, Maged
Not a big difference in both cases.
Performance of 4 nodes pool with 5x PM863a each is:
4k bs - 33-37kIOPS krbd 128 threads and 42-51kIOPS vs 1024 threads (fio
numjobs 128-256-512)
the same situation happens when we try to increase rbd workload, 3 rbd gets
the same iops #.
Dead end &
Hi,
Try increasing the queue depth from default 128 to 1024:
rbd map image-XX -o queue_depth=1024
Also if you run multiple rbd images/fio tests, do you get higher
combined performance ?
