Hi Mark, I think this CPU abuse happens independent of project size or resources. I already had modified my netbeans.conf to give it plenty of heap (2-4gb), but I’m not even running anything ‘large’ - when this happens, there are always only two projects open in the IDE - one is a library project with just a couple dozen java files and a J2SE project with less than 100 source files. Downright puny! A few years back I was working on a project with 5000 java files and NB never even broke a sweat. This bug with external changes causing NB a tizzy has been around for awhile. I think there was a way to turn external checking off, but I can’t seem to find it right now. Plus the disadvantage would be that when I do occasionally externally inject changes (eg copying an image file into the project source tree), NB might not react appropriately. :-(
Anyway, any further suggestions, let me know. Much appreciated. Tom p.s. has anyone noticed that macOS Monterey now no longer has an “Anywhere” option in System Settings->Security & Privacy->General->Allow apps downloaded from ??? Annoying as hell. It’s already refused to run half a dozen things I downloaded and wanted to run - have to manually give an exception :-( Does anyone know of a way to turn this off? I haven’t tried downloading a new version of NB lately, but macOS won’t run that either, I don’t think, without manual exception. On Oct 20, 2021 at 1:18:58 PM, Mark A.
