Yes, I'm running on 0.94.3. The last major compaction ran yesterday. It's almost daily. That's why I was surprise it took so long. I mean, I'm only compacting regions who moved. So it should be pretty quick. But was not the case. It took about 6h to complete. Strange. Maybe something went wrong when I stopped/started hbase.
also, there was almost no activity on the network nor on the CPUs. I will have to add disks monitoring on Ganglia to see if I was limited by IOs... I looked at the regions logs and everything was fine. It was showing some compaction information every few seconds.
