Hi, maybe it can help, I'm doing same tests that stefan, random write with 4K with 3 nodes with 5 osds (with 15K drives) fio --filename=[disk] --direct=1 --rw=randwrite --bs=4k --size=100M --numjobs=50 --runtime=30 --group_reporting --name=file1 I can achieve 5500io/s (disks are not at 100%) cpu is around 30%idle ( 8 cores E5420 @ 2.50GHz)
mine is 25-30% idle? May be this is the limit? So our osds are the problem? Stefan -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
