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. -- Dan Nelson dnelson@allantgroup.com
