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? - erik
