I was using rsync to copy the files from the old server to the new server and noticed that every 5-6 transfer the speeds would slow down to only 1-2MB/s and sometimes stop all together. I suspected this was due to the cache/memory getting filled up so XFS has to write the changes to the sata drive. I tried to turn off write-cache and nobarriers but still have the same problem.. When i try it on the ext3 filesystem it runs at a constant transfer speed. Is this normal with the XFS filesystem? _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
