Hi List<br><br><br>I have big write performance drop when use drbd on my SSD disk.<br>Normally i have on read 25k iops and write 10k iops when i run performance test on my SSD disk.<br>When i configure drbd in "cs:StandAlone" i have only 2k iops on write and 24k on read.<br>
<br><br>I am using drbd version 8.3.9 downloaded from <a href="http://drbd.org" target="_blank">drbd.org</a>.<br><br>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<br clear="all">
<br><br>So is this write performance drop as expected, and drbd is working correctly, or is there something wrong to cause this?<br><br>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.<br>
<br><br>Thanks<br><br>-- <br>Lucas<br>
