Roland, After applying the following configurations, the result of DRBD9 local can reach 57095 while DRBD9 export can reach 51980. drbdmanage net-options --max-buffers 80000 --resource vol3 drbdmanage net-options --max-epoch-size 20000 --resource vol3 drbdmanage net-options --sndbuf-size 512000 --resource vol3 drbdmanage disk-options --md-flushes no --resource vol3 drbdmanage disk-options --read-balancing least-pending --resource vol3 drbdmanage disk-options --al-updates no --resource vol3 drbdmanage disk-options --disk-barrier no --resource vol3 drbdmanage disk-options --disk-flushes no --resource vol3 drbdmanage disk-options --al-extents 6481 --resource vol3 The following disk options can't be applied via drbdmanage. I find if I manually configure DRBD9 and add all the options for SSD, it still can get better. So how to apply those options with drbdmanage? c-plan-ahead 10; resync-rate 400M; c-max-rate 600M; c-min-rate 10M; c-fill-target 44K; Anyway, I think the result is pretty good. Thanks a lot for your help!
