Chrome seems to tank my Air's performance. Any solutions?
Based on your question, I assume you're not experiencing problems when using Safari or Firefox (although you don't specify whether you use them or not).

Assuming that's the case, the first thing I'd try is turning off hardware acceleration in Google Chrome. To do this, follow these steps:


Launch Google Chrome
Go to Chrome > Preferences (or just press the command, keyboard shortcut
At the bottom of the page, click on Show advanced settings...
Look for the System subheading in the new settings that appear
Uncheck the Use hardware acceleration when available option
Restart Google Chrome
