If you are using Task Manager to judge sizes then be sure to notice the
difference between "Mem Usage" and "VM Size"... Mem Usage is the amount
of physical ram currently in use by a process, but VM Size is, well,
different. If you have less physical ram on a machine then you may see
less Mem Usage but more VM Size (and probably lots of page faults as
memory is swapped in and out, seen in Task Manager as "PF Delta"). I
always show both Mem Usage and VM Size in Task Manager to get a better
picture of actual memory requirements.

It seems odd to me because Jrun uses significantly less memory on both
of my other development machines (my 1GB laptop runs at under 75MB on
Vista Ultimate). The numbers I've been quoting are from Jrun just after
boot (idle, no applications loaded) or after only running CFAdmin.
Maybe Jrun needs some time to configure itself and requires extra memory
when first installed? Maybe the same can be said for when the machine
boots? I don't know, I'm merely asking.
The new box is now running at 165MB. The settings are default (as
verified earlier). I'm content with 165MB.

What makes you think that is not right? If your Max is set to 512 and
you load something as an application, the JVM will determine when to
recover memory based on it's own timetable and settings. 427 megs could
indeed be appropriate depending on the settings.
There are some code snippets on this post that you can use to fiddle
with the JVM gc operations - although I would not use them in
production.

If forcing a "stop the world" gc brings your memory back down you are
probably worried about it for nothing... Since the JVM will eventually
run a full gc on it's own.

I rebuilt my machine again. This time... no Windows updates, no
antivirus, nothing...
I immediately downloaded the latest installer from Adobe and installed
it
(Server config with all IIS websites). JRun is running at 427MB. This
can't be right??
