Laggy Action
I am running Musescore 2.0.3.1, revision 6347ed6 on OS 10.11.6.
The software becomes incredibly laggy and difficult to work with after about 10 minutes, sometimes sooner. Editing text, adding notes, anything. Mouse movement sometimes becomes laggy. Musescore uses only 10-15% of the CPU time.

My guess is you have the Navigator window enabled and it is sized to that it is right on the edge of being able to fit all pages on screen within a scrollbar. If that's the case, change the size to make it more clearly one or the other.
If not, then perhaps it is something specific to the score you are working on. Please attach it, and - if possible - gives steps to reproduce the problem.

Navigator is not enabled (though it does intensify the issue), and it is not isolated to any one score. Steps to reproduce the issue: use Musescore.

So, to be clear:
1) start MuseScore
2) enter one single notes into My First Score
3) wait ten minutes
4) check CPU usage
and it goes up to 15%? Could be some sort of hardware or driver incompatibility I guess. Have you checked the "Known incompatibilities" section of the Handbook?

Sorry, I wasn't clear.
After generally using Musescore for 10-15 minutes, note input and other changes begin to slow down drastically. Processor utilization is always at 15% or so from the get go, and it uses 0.5-2GB of RAM out of 16GB depending on the size of score.
I know it's not an incompatibility.

10-15% CPU usage right from the very beginnjng is very much not normal. Should be close.ton0. What makes you so sure there is no incompatibility? That seems the most likely explanation thus far to me based on the available evidence.
Again, if you can share a sample score and more precise steps to reproduce a problem, then we could investigate other possibilities.
only 10-15%
That is a lot, on a CPU with 4 cores and hyperthreading this is one core at full throttle
In reply to only 10-15% That is a lot, on by Jojo-Schmitz
I am running on a dual core with hyperthreading, and utilization is spread across all physical and virtual cores, not just isolated to one core doing all of the work (so each core is pulling an equal amount of weight).

OK, in that case 25% might be indicating a saturated core. Apparently not the case here, so forget what I wrote
The problem is clearly with Navigator. When it's not running everything is fine. When it's there, note entry with a mouse is impossible. Even clicking on an icon is slow to respond. It wasn't that way before I accepted the upgrade to the current version 2.0.3 rev 3c7a69d. I'm seriously thinking about going back to what works because this doesn't and Navigator is a very useful function (when it works).

Try resizing the Navigator. See:

Indeed, so have you tried Marc's suggestion above? (resize Navigator)

I looked at the length of my piece and there were hundreds??? of measures beyond what I needed. Deleting them solved the problem. Who knows where they came from. I added 25 measures at one point. Maybe it 250 measures. Solved. Thanks
As Fredrick sang to Mabel "I would if I could but I am not able". Tell me how to resize the Navigator and I'll be happy to do it. Thanks in advance for the help

The Navigator can be resized by moving the mouse cursor to the border between your score and the Navigator. When the cursor changes to a double headed arrow, drag it up/down to increase/decrease the size of the Navigator.
