This small CLI utility displays the maximum speed in kBytes per second for reading, writing and copying in RAM. If will also do a read test in ROM. MemSpeed checks the speed of your Chip-RAM, Fast-RAM and ROM by applying a buffer of 128k. The speed test routine is a loop of 64 MOVE.L instructions running in supervisor mode with interrupts disabled, which will fit in all instruction caches from 68020 on.
MemSpeed v1.1 is Freeware.
