Output of vmstat or top during the slowdown might be useful here. If editor
responsiveness is bad, you're either running dozens of cpu-hogging
processes, or running the system so far out of memory that your editor is
being swapped out while you're typing. Certain ports may require a lot of
ram to build (the jdk*/openjdk* ports possibly), but none should launch more
processes than you have CPUs.
