Notes/Summary Of Tuning Parameters

The adb tool was used to enable UDP checksumming on the load generators.
  adb -w -k /vmunix /dev/mem
  udp_cksum?W 1
  udp_cksum/W 1

The FAServer uses RAID to combine all of its disks into a single large file system.
It uses a real-time embedded kernel that processes NFS requests right from the network
layer without and NFS daemons.  It uses non-volatile RAM to improve NFS performance.

To run the SFS benchmark, configure the FAServer by adding this line to /etc/rc:
  options minra 1 nosnap 1 nosnapdir 1
