Hi Ceph users,
Im working on common lisp client utilizing rados library. Got some
results, but don't know how to estimate if i am getting correct
performance. I'm running test cluster from laptop - 2 OSDs - VM, RAM
4Gb, 4 vCPU each, monitors and mgr are running from the same VM(s). As
for storage, i have Samsung SSD 860 Pro, 512G. Disk is splitted into 2
logical volumes (LVMs), and that volumes are attached to VMs. I know
that i can't expect too much from that layout, just want to know if im
getting adequate numbers. Im doing read/write operations on very small
objects - up to 1kb. In async write im getting ~7.5-8.0 KIOPS.
Synchronouse read - pretty much the same 7.5-8.0 KIOPS. Async read is
segfaulting don't know why. Disk itself is capable to deliver well
above 50 KIOPS. Difference is magnitude. Any info is more welcome.
