Hi List
I have big write performance drop when use drbd on my SSD disk. Normally i have on read 25k iops and write 10k iops when i run performance test on my SSD disk. When i configure drbd in "cs:StandAlone" i have only 2k iops on write and 24k on read. I am using drbd version 8.3.9 downloaded from drbd.org. I tried to change tuning parameters like described in "Part V. Optimizing DRBD performance" but it doesn't help to get result near 10k on write So is this write performance drop as expected, and drbd is working correctly, or is there something wrong to cause this? I do not post my drbd config file, because i have lots of them, and they didn't allow me to get more that 3k iops on write. Thanks -- Lucas
