Hi.
ceph osd pool set data size 1
dd if=/dev/zero of=aaa bs=1024000 count=4000
4096000000 bytes (4.1 GB) copied, 31.3153 s, 131 MB/s
ceph osd pool set data size 2
4096000000 bytes (4.1 GB) copied, 72.7146 s, 56.3 MB/s
ceph osd pool set data size 3
4096000000 bytes (4.1 GB) copied, 136.263 s, 30.1 MB/s
Why? I thought increase in the number of copies should increase the
performance (in the worst case does not affect).
WBR,
Fyodor.
