I'm in the same position.
Meter is the worst I've ever experienced today.
I'm using MacBook Pro with Chrome (version 33.0.1750.117) and an older Flash (11,6,602,171). I've had issues with a strange process appearing in the Activity Monitor called Google Chrome Helper EH that takes up a large chunk of CPU %, and the computer fan goes into overdrive. In the past, it's been an intermittent issue, solvable by clearing caches, and rebooting everything... but today nothing seems to help, and it's just out of control.
If anyone else has seen this, and can suggest a fix, I'd love to hear it. Thanks!
