Apologies for the long delay.... Unfortunately, I can't reproduce any of
this at all: I reliably get about 112MB/s regardless of what combination
of these patches I apply (including none).  This is over gigabit
ethernet to a server exporting a filesystem on raid 0 over 3 sata disks
which iozone locally reports getting just over 200MB/s reads from.

Any suggestions?
