[comp.sys.ibm.pc] Desqview & disk caching question

wolf@cbnewsh.att.com (thomas.wolf) (05/02/91)

Since my last query got such a good response, I thought I'd try again :-)
(BTW, if my q's seem naive, it's because I just recently got a PC...prior
to that I was a 100% UNIX person: no additives, no preservatives...:-)

Windows 3.0 comes with a caching program, SMARTDRV, that all my PC friends tell
me is one of the slowest caching programs available.  I've been using this
cache program under both Desqview and Windows without problems.  But because my
friends were all using (and highly recommended) "superpck" and "hyperdisk"
(and one can always use that extra smidgen of performance),
I went out and got a copy of each and tried them on my computer - expecting
major performance gains...No dice.  Sure, under Windows3.0, both of these
programs blow away SmartDrv, but under Desqview (my development environment),
SMARTDRV outperforms the other two.

A couple of words as to how I 'benchmarked' the caches:  I just used a stop-
watch to see how many seconds a "make" (Borland C++) of one of my programs
took.  Here are the relative numbers (as I recall them):
		WINDOWS3.0	DESQVIEW	NONE
SUPERPCK	23		21		11
HYPERDSK	21		20		11
SMARTDRV	33		15		13

For each cache, I used the defaults, as applied by the install procedure.
(BTW, SUPERPCK seemed to do strange things to my system: occasionally hanging
it, and, after changing a few options, causing my harddisk to go beserk(sp?).)

I know that there are all sorts of options you can set with these programs,
and in the case of superpck I have (one setting brought superpck's performance
to within a second of SMARTDRV when in DESQview).  My question is: has anyone
had similar experiences - ie. found caches to be slower under DESQview when
they're normally faster than SMARTDRV?  Also, if someone has found an "optimal"
setting for these programs under DESQview, I would really appreciate it if
you told me - I'm a little disappointed that I can't get better performance
out of superpck after spending $80 on it.

Just in case hardware setup makes a difference, here's my setup: '386 clone
with Awards BIOS, 4Meg RAM, Orchid ProII, UltraStor ESDI controller and
Maxtor 150Meg ESDI drive.  QEMM 5.12 (with the patch suggested by superpck),
DESQview (newest version, can't remember what it is).

This setup doesn't seem to be out-of-the-ordinary but, as I mentioned above,
it does cause superpck to hang the system on occasion.

Thanks, in advance, for any help/info,
Tom
