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.
