I removed the arbiter and created a new full brick. This resulted in two bricks in sync with each-other, with just over 100.000 small (average 10 KiB) files, and one empty brick. The healing process started populating the empty brick at a really slow rate of something like two to five files per minute. I would have expected one of three things to become saturated at least on one of the participating machines: or the network, or disk I/O, or CPU. But far from it, nothing is even close to saturated. On all three machines the CPUs (top) are running almost idle, disk I/O (iotop) is negligible and network traffic is in the order of 100 Kbps. It looks like 'nice -n 700 glusterd', on a nice scale from 1 to 19. Any ideas where I should look for the bottleneck? I can't find anything even remotely relevant in any of the logs.
