Thank you to everyone who responded. I'll try to address the comments
and suggests I received.
Yes, this is a Java project. It uses Ant because, to the best of my
understanding, Ant is required to do cross development and debugging for
a Raspberry Pi. If that is possible with Maven, I don't know how to do it.
When all Java, HTML, and a few other resource files are counted, the src
directory contains 294 files, 35 folders, and about 3.8MB of data in total.
I had already closed all other inactive projects. So only the single
project I was working on was open.
I had already given NetBeans more memory by editing netbeans.conf to
include -J-Xmx2g . I had a suggestion to raise this to 6g. I haven't
done that yet since 2g is about 3 times more than any actual memory
usage I've observed in Task Manager.
I had also already deleted the cache about a week ago, but I did that a
second time yesterday.
First I closed the only open project, then shut down NetBeans, and then
deleted the cache. I restarted NetBeans and let it load completely, at
least as best I could determine that by watching status messages at the
bottom of the window.
With NetBeans up and running, I reopened the project and let it scan
until complete. This took somewhere between 60 and 70 minutes. I
assume that scan was rebuilding the cache.
Subsequent re-launches of NetBeans are taking 20-25 minutes to reopen
the project and complete all the initial scans. But I would say, at the
moment, that NetBeans is more responsive than it was. Not great, but
better.
Although the project files are on a file server, I really don't think
that is the issue. The file server and network (gigabit) appear barely
utilized while NetBeans scans away.
And NetBeans appears to spend large portions of time scanning unchanging
(I assume) NetBeans and Java files in the C:\Program Files. NetBeans
itself is installed on the C: drive.
As a test, I also reopened an older project that is almost the same size
as the current one using NetBeans 12.6 on the same computer using the
same file server. That older similar project opened and completed all
scans in about 5 minutes using NetBeans 12.6.
At the moment I've been spending my time testing. I need to get back to
work on the project to see if the performance improvements I did see
after deleting the cache can be sustained.
