Slow performance

[Steven Adams]

Hi All,

I am using XFS for the first time of one of my servers. 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?
