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
