Hello Daniel, just throw away your crappy Samsung SSD 860 Pro. It won't work in an acceptable way. See https://docs.google.com/spreadsheets/d/1E9-eXjzsKboiCCX-0u0r5fAjjufLKayaut_F... for a performance indication of individual disks. -- Martin Verges Managing director Mobile: +49 174 9335695 E-Mail: martin.verges@croit.io Chat: https://t.me/MartinVerges croit GmbH, Freseniusstr. 31h, 81247 Munich CEO: Martin Verges - VAT-ID: DE310638492 Com. register: Amtsgericht Munich HRB 231263 Web: https://croit.io YouTube: https://goo.gl/PGE1Bx Am Di., 13.

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. Daniel Mezentsev, founder (+1) 604 313 8592.
