I have used CD Speedway from Bloc Plublishing. It does a good job of
caching repeated reads of data. It will cache to any DOS drive device, eg.
C: D: or a ramdisk (preferable). I don't think it really does much in the
way of read-ahead though, and that is what is really needed for CD-ROM
improvement. If you are doing repeated reads of the same data and have a
few megs of RAM to spare, it will work well.
Ramon,
Thanks for your comments. My position on read ahead is that since Speedway
pulls the entire file into cache, chances are more than the CPU requested
will remain there and 'may' be used.
Hard disk read-ahead offers limited benefit except on sequential
track/sector benchmarks like coretest or sysinfo.
I apreciate your feedback. You may see better improvement in your
situation if you use a hard disk based cache. The reasoning is that a 2-4
Meg. Ramdisk won't work as well as an 8-12 Meg. hard disk based cache with
a supplemental disk cache in RAM.
