Google Chrome running alot of processes?

So ive noticed recently that google chrome runs on average a total of 10+ processes everytime its used. No matter how many tabs I use; 1, 2, 18; There is always an abundance of processes running which I feel is unnecessary? The screenshot shown here is with Chrome completely closed and not running. But its 15+ processes still are...why? Is it all of the add ons and extensions? :I Shouldn't they...close and stop running...when the browser dose too...?

Come to think of it...isnt 117 in and of itself alot too? The only program really actively open and running at all times constantly is MSN. Hrm...I dunno.

 

Chrome uses a separate process for each tab, addon, and extension. It ends up LOOKING like a lot, but it makes it much more stable and faster (can be run on multiple cores, etc)

 

117 actually is a lot, I'm at 52 wih 7 Ultimate and Nightly's two processes.

 

Try go to Google Chrome's Option, Under the Hood, go to the bottom, untick "Continue running background apps when Google Chrome is closed"

You cannot blatantly say that X number of processes is a lot. You need to understand how some programs work. Unfortunately, unless you know exactly all the programs you have installed and how each and every single one of them work, you cannot judge based on X number of processes.

That said, Google Chrome is highly threaded. Each tab runs in its own process. Each tab's flash or other content runs in its own process. Each extension has its own process. It's not surprising to sometimes see Chrome with 50 processes.

It is possible that either Chrome hasn't successfully exited or that you have "Run in background" checked.

 

All plugins have their own process. The javascript renderer has its own process. Each tab has its own process. The updater has its own process. GPU has its own process. Extensions have their own process.

This leads to enhanced performance, stability, and security.

If Chrome is closed and these are still running do what Lee_what2004 said.
