Please everyone that is bitchin' about 3.0 speed try booting with more system buffers, the difference is phemonal, even on a lowly '030 with only a 40meg swapdisk. I haven't played with the swaptimizer stuff at all. - From hardy@714-725-3176.nts.uci.edu I avoided the 12 character limit by using the startup (in p in the rROM monitor) sd- nbu=128; seems to work fine; I also added compressed swapping, hoping to avoid huge swapfiles. Regards, Hardy ----- - So to change the boot params use cmd-cmd-~ to halt the machine and get to the ROM level prompt ie NeXT> Then type p and answer the questions appropriately. TRY IT, IT REALLY WORKS... -I've found 64 to work fine for me on a 20meg '040 Mono NeXTstation. - Booker C.
