How many tabs did you have open at the time?

If you had all that usage in only one tab, I suggest closing and re-opening Chrome.

Do you have "click to play" turned on in Chrome? If you run Chrome with a lot of tabs open, it can really use a lot of resources. Turning on click to play means you don't wind up with 78 instances of flash chewing through resources in 80 tabs.

Thanks for your help I have 39 tabs open right now, 4 are youtube documentaries I've been meaning to watch for the past week but never had the time! two soundcloud tabs, and the rest are just articles, I'm sure only a few are flash based. I attached a screenshot of my activity monitor.

I have 17 tabs open. Memory used is 6.15 out of 16 GB. Your screenshot shows 600+ meg of swap but I have NO swap. I use click to play so I know that NONE of my tabs have flash open in the background. I would think that turning on click to play would give you some relief. May I also suggest "too many tabs" so you can send inactive tabs to tmt which makes them consume 0 resources.

It would seem that flash player alone has 90 threads. 90! And it has the single largest slice of CPU on your entire screenshot: 6.3 percent.

As I composed my response, I decided to click to play NASA's "Big Blue Marble" flash video. Flash instantly ate up 13 percent of my CPU then went away when I reloaded the tab (causing flash to be closed and the click to play puzzle piece to come back).

It started to really piss me off when it started lagging a bit, whenever I connect my iPod classic and wanted to transfer music, iTunes would freeze and the activity monitor showed it was "not responding", which is the thing I hated the most about Windows, never seen those words on a mac before and I've been using macs for 4 years! And yeah I noticed the Chrome flash plug-in, I also didn't understand why the Chrome Renderer was hogging so much RAM, so I looked it up and found this!

I switched to Safari and moved all the same tabs to Safari, I got back around 2GB of RAM, then I installed Click to Play and reloaded all the tabs and got back another 2GB or so of RAM.

It's a bummer though, as much as I love Safari I loved the Presentation view on Chrome more, cuz it goes further than just a full screen view and hides all the tabs and menus ...

Thanks a lot for your help r0k!
