[Gluster-users] software raid performance

Are there known performance issues with using glusterfs on software raid? I've 
been playing with a variety of configs (AFR, AFR with Unify) on a two server 
setup. Everything seems to work well, but performance (creating files, 
reading files, appending to files) is very slow. Using the same configs on 
two non-software raid machines shows significant performance increases. 
Before I go a undo the software raid on these machines, can anyone confirm if 
there are known performance issues with software raid? Or if I should be 
hunting down other differences between the two environments (there may be 
other differences such as kernel versions, 64bit vs 32bit, etc.)? In both 
environments I'm using 1.3.9.
