- Short: Utility to check speed of RAM and ROM.
- Author: frank@phoenix.owl.de (Frank Wille)
- Uploader: frank@phoenix.owl.de
- Version: 1.1
- Type: util/cli
- Requires: OS2.04
-
- 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.
-
-
- Here are some results I got by using MemSpeed on my
- A4000/040 (instruction cache was always enabled):
-
- ScreenMode DataCache ChipRAM r/w/c FastRAM r/w/c ROM r (MB/sec)
