As it fills up, I have seen a big dropoff in function -- programs load

What is the recommended amount of HD space to keep free for good
performance?

 That would depend on how much RAM you actually use, but the general
recommendation is to keep 10-20% free on the startup drive, depending on
how much your system swaps due to low memory conditions. You're way
short of that 100 GB (10%).

OK, thanks!  Now I know what to aim for.  Luckily, it will not be too difficult to accomplish -- loads of stuff I can get rid of.
Should I defrag afterwards?  Or does the OS (10.13.6 High Sierra) make it somehow unnecessarry
