On the topic of Chrome performance tips, if you always have dozens of open tabs in different windows, this nifty extension will freeze them out (unload them) until you actually want to look at them again : https://chrome.google.com/webstore/detail/the-great-suspende...
In theory, this is what memory paging is for. In practice, this is higher level and seems to work much better.
I disabled it after a while. Its time lapse can't be changed although available from setting. It tends to suspend tab within a couple minutes and constant reload when switching between tabs. Very poorly developed, a nice idea though. A similar addon in firefox has done this long time ago and I can keep over hundreds tabs in firefox almost all the time, while only a few is loaded.
