- In trying to troubleshoot a problem with my tape backup software
- (Central Point Backup, in case the word *problem* didn't give it
- away) I was experimenting with turning Smartdrv on/off. To be
- honest, I couldn't tell any difference in system performance!
- I had to keep referring to my autoexec.bat to see if Smartdrv was
- running or not. This was a surprize to me, so I specifically
- tried loading large-ish Excel spreadsheets with and without
- Smartdrv since I figured this would generate a bit of disk
- access. Any differences were not evident to me. I know my
- brain is not as accurate as a crystal controlled timer, but
- I would have expected at least a slightly perceptible difference.
- From previous tests with Smartdrv, I know my cache hit rate was
- between 80-85% (not all that great - I know.) Maybe the kind
- of applications I run are not disk intensive enough to make
- disk cacheing all that important for my situation?
