not really. a kernel compile from ramfs took about 2.9s with an
average of more than 3s of cpu used for every second of real time. a
compile from the fs over a gigabit link took about 1s longer, but used
far less cpu.
neither is particular impressive, but i'm not using a great percentage
of the cycles available ( ~3/8) and i am using the slowest processor on
the sheet and, due to my misreading of the datasheet, i have only half
the memory channels populated.
did you have anything specific in mind?
