I assume this is because of not enough swap space on the HD.

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%).
