Hello list, i've done some benchmarks regarding striping / v1 / v2. Results: format 1: write: io=5739MB, bw=65278KB/s, iops=16319, runt= 90029msec read : io=5771MB, bw=65636KB/s, iops=16408, runt= 90030msec write: io=77224MB, bw=874044KB/s, iops=213, runt= 90473msec read : io=178840MB, bw=1983MB/s, iops=495, runt= 90168msec format 2: --stripe-count 8 --stripe-unit 524288 -s 4194304 write: io=5377MB, bw=61147KB/s, iops=15286, runt= 90041msec read : io=5332MB, bw=60617KB/s, iops=15154, runt= 90067msec write: io=75136MB, bw=849285KB/s, iops=207, runt= 90593msec read : io=160292MB, bw=1777MB/s, iops=444, runt= 90226msec --stripe-count 4 --stripe-unit 1048576 -s 4194304 write: io=5301MB, bw=60281KB/s, iops=15070, runt= 90046msec read : io=5367MB, bw=61031KB/s, iops=15257, runt= 90057msec write: io=74448MB, bw=840293KB/s, iops=205, runt= 90724msec read : io=170616MB, bw=1891MB/s, iops=472, runt= 90227msec So it seems right now that striping doesn't improve performance.
