- No, but the normal cache setting for OS/2 is
- a poor choice for anyone with 8 megs or more.
-
- We can assume that either NT is the same (and the original
- user, with 16 megs, has adjusted it) or that it auto-adjusts.
- If the later, then my argument is eliminated.

- I do not know whether it does or not. But I am *certain*
- that if it does not, the previous owner would have fixed it
- for his 16 meg system.

- Such a system would not have "parameters carefully selected"

-
- You're thinking like a dos user. It is not a bad idea to have
- the system auto-adjust and *allow* the user to fix it when you're
- talking about something that's suposed to be user friendly.

-
- ...only if you then took *that* setup (the one optimized for
- 16) and moved it *back* to a 6 megger w/o *any* change.

- OS/2 behaves funny when you have low memory and are using
- the HPFS. IBM tech support themselves will recommend
- not using HPFS if you have less than 8 megs and I have
- been told this is not only because it slows the system to
- a crawl, but because a system with the swap file on an
- HPFS partition with 6 megs or less will have problems
- (I was told this two seperate times by two seperate IBM techs).
-
- I think there's a comment to this effect in the faq, too.

- Obviously, you never used the 2.0 beta, which became
- about 90% less stable when it started to use virtual memory.
- This was before they plugged most of the big holes
- in VM. VM is not something simple, it is just more room
- for bugs to hide in. So what this guy is doing is roughly
- equiv. to running the OS/2 beta in 4 megs--with it
- configured for 8--so *of course* it's slow and unstable.
-
-
-
- >remain as stable or unstable as it was before the memory change.
-
-
- Nope. OS/2 had more than it's share of VM induced
- instability (still does, probably--might explain some
- of those funny "impossible to explain" crashes, but it seems
- pretty solid since the SP).

- Think a little more before such comments.
