Hi ,
I am not sure why PG numbers have not given that much importance in the
ceph documents, I am seeing huge variation in performance number by
changing PG numbers.
Just an example
*without SSD* :
36 OSD HDD = PG count 2048 gives me random write (1024K bz) performance of
550 MBps
*with SSD :*
Hi
I have installed 6 node ceph cluster and doing a performance bench mark for
the same using Nova VMs. What I have observed that FIO random write reports
around 250 MBps for 1M block size and PGs 4096 and *650MBps for iM block
size and PG counts 2048* . Can some body let me know if I am missing
