[Gluster-users] read and write speeds

I'm testing gluster/nfs for replacement of an existing DRBD/iSCSI system.
Speed tests show gluster NFS to be pretty close to iSCSI, but I have some questions.
If I do a sequential write of data, I get ~118 MB/s. A sequential read of data gets about 65 MB/s.
If I do a sequential read and write at the same time, write speed drops to ~100 MB/s while read speed drops to about 10 MB/s.
Does anyone know why this occurs, and is there anything I can do to speed up the read speeds, maybe make reads and writes a bit more balanced?
