- I installed OS/2 2.0 last summer and have recently upgraded the 386 on
- which it is isntalled from 8 meg to 16 meg of RAM. When OS/2 installed
- itself (with a FAT partition) it set aside a 384K diskcache. With the
- extra RAM I decided to try a 1024K diskcache. After rebooting to
- make the change I tried the following:
-
- pkunzip -t largefile.zip
-
- There was of course some disk activity. Then I tried it again, thinking
- this time it would all be in the diskcache. It ran in the same amount
- of time with what seemed like the same amount of disk activity. I tried
- the same experiment with DOS 5.0 and SMARTDRV. In DOS, the second time
- I did the pkunzip -t command there was no disk activity at all but it
- ran only slightly faster. Is SMARTDRV merely a reflection of the last
- 1024K bytes of disk IO? Is OS/2's diskcache doing something different,
- perhaps more efficient some how?
-
- Thanks for any help!
