I haven't gotten into the hardcore benchmarks yet, but have this to report: I'm burning in a new asus p6np5 machine by making the same -current world, over and over and over again, with an intervening 'make clean' in /usr/src between each. With 128MB (2x16x36) and an async /usr, i see no difference in the mw build time between checking nothing and doing ECC. I would think that with cc -pipe set and all of that memory I would be exercising the memory enough for me to see a difference in the time (1:51). This is a full world with CFLAGS= -O2 -m486 -pipe, and compressing man pages. Of course I have no way of knowing if the bios itself is hokey and just isn't doing anything whether I have ECC set and the 'data integrity' switch set that enables it on... -Chris
