This approach sounds interesting but would you please explain more about
the cache. I am aware that my computer has a swapping file which is managed
in size by the Windows system program or may be set to some amount of fixed
memory for each of the minimum and maximum values. I am aware that setting
both max and min values to one value a sufficiently high value for ones
programs; this approach I found from my experience achieved an increase in
operationally speed. I believe it may have been accomplished because of
faster data transfers.
Is this cache memory something different? I believe all of our group should
comprehend computer functionality because most of us at some time in the
future shall be considering purchase of an improved computer .

Here is my personal thoughts, it won't be what people will generally say,
but it is quite easy to find out if you are using several OS and compare
them, ie. Win 95&NT vs. Linux).
I am not using MS PRO, and what I do are genrally explorations on 9000
stocks to detect some patterns, divergence and so on on all stocks. What I
want is those explorations to be run as fast as possible, and I want smotth
screen output as well.
What I found is is somehow amazing : The CPU power on WIN 95/NT is not the
key element of the overall PC performance. Memory and hard disk have the
most impact on response time on explorations.
I have a K6-233 I bought a year and a half ago (so said "old CPU"), NT4
workstation. What I monitored is bottleneck is made on disk activity while
exploring. I switched from an average exploration time of 17 minutes to 6
minutes just by using a good hard disk write behind cache program. I made
test on a PII 350 MHz, NT4, 256 Mb RAM without hard disk write back cache,
and again, I got explorations of 16 minutes.
More than 32 Mb of my 96 Mb Memory are dedicated to cache. I consider
upgrading my system to a Celeron 350 MHz or K6-2 350 or whatever, but
emphasize the PC upgrade on memory (256 K RAM or 512 Mb RAM) and real fast
hard disks.
I wish I had 1 Gb RAM and then I would do MS explorations in RAM disk with
background writes to the Hard disk, I am sure it will really give blasting
performance.
So my advise would be : make sure you have the best hard disk, or even
consider RAID 0 disks (stripping) with write back cache. But all I say is
for explorations (i.e regularly scan the databse for patterns and so on).
My
problem might be totally different from yours.

Hi,
I am about to upgrade my current PC which is an NEC PII 233mhz. I am
not an expert when t comes to hardware and therefore seek views as to an
appropriate upgrade.
Its main use would be for running metastock pro, excel, word, netscape
etc and it would be part of a LAN network. I don't think I would be
using it for any heavy duty graphics.
Browsing the shelves of Comp-USA it looks like my choices are between an
Intel Celeron, PII or PIII. Can anyone give some suggestions and in
particular describe the differences between the 3 processors? Whatever
the choice, I would have a minimum of 64meg or RAM and would prefer to
use win95.
Also as a bechmark, which Celeron chip would be the equivalent to my
current PII 233mhz?
Email direct if you prefer. Thanks in advance.
Essan Soobratty.
