Hi, I've also had problems with DRBD incurring (unreasonable, I would say) additional write latency on my systems. I've been watching this list since last July, and have seen a number of people report similar-sounding problems, but have yet to see any real explanation of why this happens or any solution to the problem. The earliest version I've used was 8.3.7, so I can't really speak to whether or not 8.2.6 was any better in this regard. (I did try updating to 8.4.0, but that didn't seem to help and introduced other problems, so I returned to 8.3.x.) For what it's worth, when I updated my servers from RHEL5 to RHEL6 (so a 2.6.18-based kernel to a 2.6.32-based one), it "felt" like things may have improved slightly, but not a whole lot (I say "felt" because I don't have any hard before/after numbers on it).
