PC configuration for W4GL

In INGRES/W4GL release notes [april 94] w4gl 2.01/01 (dev.win/02 &
run.win/02), it provides the PC configuration requirements;HOWEVER, I
cannot (re)locate the required RAM for a development PC.  I believe
INGRES recommends 16MB RAM (or was that 12).  I am interest in the
configuration of current developement RAM on PCs (NOT INGRES' MINIMUM).  
What is the wisdom on PC RAM for W4GL?

Since you are using the last version of the release 2 on PC series
a number of memory leak bugs were taken care of (that's the good news).  
We built and tested the W4GL for Windows product on 16MB and 32MB
machines.  Some of the tests involved opening, editing and compiling some
rather huge customer applications.  16MB seemed to be sufficient for the
job, at least when we didn't have any other memory hogging programs on
the machine.  I would define memory hogging programs as most 4GLs (Gupta,
Powerbuilder, Forte), many high feature graphics applications and
anything with a footprint of 4MB or more.  If you are wanting to run any
of these other applications concurently you will definitely want 32MB on
your machine.

I seem to remember that the memory footprint was around 5MB for the
virtual engine and that we used up a lot of GDI resources.  
If you are in a position to move to OpenROAD (W4GL version 3) you
will be in a much better position in terms of memory, since memory and
performance were two of the prime goals of that release.  It also has far
fewer bugs.

1. W4GL PC Configurations

We are currently using W4gl 2.0 under Windows3.1 on 486/33's with
8-16 MB memory, and 110 MB HD.  We have alloted a 10MB permanant
swap file.  Our concern is that because our application is very
'frame intensive' i.e., users can have up to 7 - 12 frames open,
and a few of these frames are very 'maths' orientated ( ie,
between 20 - 500 calculations in one go), we may have problems in
the memorey area.  Can anyone tell me if Ingres will utilise the Windows
swap file, and if so, how and when does it use it?  I'm a bit suspicious
that the WIndows/Ingres/DOS (Whatever) swapfile management is not
up to par.  Any advice will be appreciated.

PS.  We are implementing Client server, and therefore expect the clients
to do some of the work.  Also, my personal opinion is that PCs are crap,
and we have made a decision to move to workstations, but this will take
awhile, so I have to live with what's thrown at me.

Cheers
