Thanks for all the advice.  Here is some follow-up.

I upgraded to 8 sticks of 32 Meg Hundai parity SIMMS (total 256 Megs)
obtained from SMI in Carrolton, TX. (Highly recommended!!)  This
transformed my DEC Alpha 300XL from a "dog" into a "gazelle"...WOW! 
This machine has moved from being the house "dog" to the front of the
pack.  Before, I had just 64 Megs of RAM.

Before the upgrade, KDE took forever to start, and when I started
Mozilla 0.9.5, it would go into a continuous disk-access mode (swap??)
and would not load any web pages.  I knew it worked, because I could get
it up under GNOME, but still slowly.  Now everthing starts in a
resonable amount of time, and Mozilla will bring up web pages as fast a
anything I have around the house even when run from KDE.  Performance is
now comparable to my AMD K6/2-500 machine, which is the fastest machine
I have here.

I would highly recommend a RAM upgrade if you can afford it.

BTW, mucho thanks to those who got KDE running on the Alpha (Chris??).

Cheers,
