Over the last week or two, I've noticed that my Mac seemed to be active a lot more often than I thought it should be - and when it was, there was always a "Chrome Worker" eating the CPU. It had gotten to the point where it was impacting the performance of everything, including games. I finally started disabling extensions (I have very few) last night, and sure enough - it was "AdBlock Plus". I turned that off, and I must have gained 10 fps in "Dishonored" (which I play in a Windows VM) immediately.

Chrome also got faster - pages that had been hanging, or taking forever to load, started loading right away (even on crappy hotel wifi).

I'm leaving that extension off - whatever it was doing (and I wasn't seeing fewer ads, that's for sure), it wasn't good.
