DISKPERF Disk performance benchmark. If your Amiga configuration is substantially different from the ones mentioned here, please run the benchmark and report the results to either: ..!philabs!sbcs!rick or posting to comp.sys.amiga. Thanks! To run diskperf, simply type: diskperf [location], e.g. diskperf ram: You will need at least 256K free bytes on the "disk" you want to test. Disclaimer: This benchmark is provided only for the purpose of seeing how fast _your_ system runs the program. No claims are made on my part as to what conclusions may be drawn from the statistics gathered. Just consider this program the "Sieve of Eratosthenes" of disk benchmarks - haggle over the numbers with friends, etc, but don't base purchasing decisions solely on the numbers produced by this program.
