I just ran that famous RAM benchmark that came down -hackers some time
ago:

normal parity RAM (8x 32 MB installed)
49005fb0   0.160 uS/op 6.24e+06 op/S 23.805 Mb/S
8938c0df   0.369 uS/op 2.71e+06 op/S 10.338 Mb/S
49005fb0   0.160 uS/op 6.24e+06 op/S 23.806 Mb/S
8938c0df   0.369 uS/op 2.71e+06 op/S 10.337 Mb/S

EDO w/o Parity (2x 16 MB installed)
49005fb0   0.159 uS/op 6.29e+06 op/S 23.999 Mb/S
8938c0df   0.366 uS/op 2.73e+06 op/S 10.421 Mb/S
49005fb0   0.159 uS/op 6.29e+06 op/S 23.999 Mb/S
8938c0df   0.366 uS/op 2.73e+06 op/S 10.422 Mb/S

I don't beleive one can speed up any real application using EDO.

The machine is a newer ATX double-P6 board, only one P6 installed, 512
KB cache, FreeBSD-2.1.5.

Nice box, BTW...
