- EVAL.PAS/EVAL.EXE -- Disk Cache Strategy Performance Evaluator
-
- This program estimates the effectiveness of disk caching strategies using
- a log of up to 8196 actual disk transactions from your first physical hard
- disk. The TSR program SNOOP.COM maintains the log in memory.
-
- This version of the program compares the performance of a simple write-
- through cache to the performance you'd get from no cache at all. It bases
- its speed estimates on hard disk characteristics you enter, rather than on
- the actual characteristics of your machine, so you can see how drive
- characteristics affect both system and cache performance. You can test your
- own cache strategies by defining objects of the type CacheStrategy. You can
- also observe the performance effects of cache size. As a simple experiment,
- try reducing the cache size to 64K or 128K and press G to simulate the
- results. You should notice a dramatic drop in cache performance.
