I think I may have found part of the issue ... plugin-container places a very heavy load on the system. When a user goes to a site which is using flash, it seems that plugin-container will launch and that then starts to place a very heavy load on the system. I found a discussion here: http://kb.mozillazine.org/Plugin-container_and_out-of-process_plugins
I have disabled plugin-container and the system is back to its typical, acceptable performance.
