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?W1
     udp_cksum/W1
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
any NFS daemons. It uses non-volatile RAM to improve NFS performance.
