Notes/Summary Of Tuning Parameters
Note: Storage Processors are referenced as SP0, SP1, SP2; File Processors as FP0, FP1, FP2, FP3; Ethernet Processors as EP0, EP1, EP2, EP3.
All Load Generators used same LADDIS Mount Points list with same /etc/fstab entries.
The LADDIS Prime Client was the server Host Processor (no router was needed). ThinNet Ethernet cables/transceivers were used.
The adb tool was used to enable UDP checksumming on the IPX load generators.
adb -w /vmunix/dev/kmem
