Hi All,

I am using XFS for the first time of one of my servers. I was usingrsync to copy the files from the old server to the new server andnoticed that every 5-6 transfer the speeds would slow down to only1-2MB/s and sometimes stop all together.

I suspected this was due to the cache/memory getting filled up so XFShas to write the changes to the sata drive. I tried to turn offwrite-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?
