I had ~1GB swapped out on 32GB 3.4GHz quad i7 machine. 5GB was taken up by ~8 tabs in FF. I noticed it because IntelliJ and Android Studio started to be suspiciously laggy. I mean laggier than usual :) After stopping FF, the IDEs went back to normal. Processor usage was negligible when I was not touching the system, so it wasn't caused by some runaway js code on some webpage.
