This was my mistake - I had changed the export to sync for a test right before the debug runs and forgot to change it back. > Could you please try using > > echo "9" >/proc/sys/sunrpc/nfs_debug Files should be up there (http://magicbus.cac.psu.edu/nfs). I do have to admit that something odd is going on - 2.4.22 still is faster than 2.6.0-test9-bk17 and test9-bk17 is still showing the large amount of commits, but both of them are running faster than they did before on the sync mounts and I'm not sure what I might have changed to cause this.
