4 Mb of memory on a DN3000 is ok for editing, text processing and the
like. If you are doing debugging (ie. using the Apollo DDE debugger) or
compiling on the node, you will want 8 Mb of memory. The SR10 debugger
is a memory hog, and the compilers will page thrash when compiling any
file of more than 100 to 200 lines of code on a 4 Mb machine.

We have booted 2 Mb diskless DN330's under SR10.2 and they are *slow*.
You can only work in one window at a time with any speed. Trying to
compile even a small program in one window while editing a file in
another is almost impossible due to the poor response of the DM editor.

In general, a 4 MB machine running SR10 acts more like a 2 Mb machine
running SR9.7, and a 2 MB machine running SR10 has the response of a
1 MB machine running SR9.7.
