Saving memory usage in NeWS will improve your performance,  and especially
on a 4M machine.  The suggestions you make look sensible.

However,  it turns out that the most important way of saving memory
on 4M Suns is configuring your kernel correctly.  This is especially
true with SunOS4.0,  and the initial documentation that went out
with 4.0 didn't give you a whole lot of help doing so.

The first and most important thing is:

	NEVER RUN A GENERIC KERNEL

	The only thing generic kernels are good for is to configure
	other kernels.

Beyond that,  you should read Appendix E. of the current SunOS4.0
Read This First.  The RTF has recently been updated - if you don't have
an updated copy ask your salesperson or TSE.  Appendix E gives a good
deal of detail about how to configure your kernel to save the maximum
amount of space.  Depending on which of the hints you are able to use
in your configuration,  you can save up to half a megabyte of wired-down
memory (that is what I was able to save on my 4M 3/75) as compared to
running with the default (in my case SDST75) configuration.
