Firefox easily outperforms Chrome

[Lil' ½ Dead]

When you start to scale that performance Chrome apparently falls flat on its face. What we are talking about here is having multiple tabs open, which is a very common practice today due to the amount of content we like to look at.

Chrome is great for general usage up to a certain point, but when you start opening a lot of tabs it can’t cope. It’s closest rival–Firefox, can though, and in fact excels at coping with hundreds of tabs.

To do this he used a script that opens 150 of the most popular websites in a browser instance automatically. One page is opened in a new tab every 1.5 seconds. On the latest Firefox nightly build that process takes roughly 6 minutes and 14 seconds. On Chrome, it’s a totally different story with the time escalating to 28 minutes and 55 seconds. That’s well over 4x slower than Firefox.



In fact, Wagner found that once you get past 70 tabs Chrome really starts to struggle. The reason seems to be down to the different way in which each browser handles data and tabs. Chrome uses a multi-process model where a new process is started on a per tab basis. Firefox takes a different route and has a single process running that handles all tab data.

It seems that either through a bug or design issue Chrome doesn’t end up handling every new tab as a new process. Instead some processes can end up having to cope with multiple tabs and it’s also handled unevenly e.g. one process has 2 sites where as another has 20 sites.

At 150 tabs open this leads Chrome to stop responding and max out memory use at 5GB. Firefox on the other hand only used 2GB of memory and continued to work under the same conditions.

What is the difference between the two in a real-world scenario though? No normal user is going to have more than eight or nine tabs open at a time, so how big is that performance gap then?

"However, up to a certain point, and probably for the majority of users, you aren’t going to experience this problem."

Ah, nevermind.

Thanks Lil' 1/2 Dead for the interesting article and tuning into the Gregor Wagner’s blog page for further reading.Might be just the thing to check out the script for kicks .I dunno only have 4GB ram installed.Still going to stick with FF or one the Nighfly builds.

Tops, I have 10 Tabs open at once, and I still use IE9. I am using a MS OS so I will use the MS browser, when Chrome or Firefox makes an OS than I will use their browser. I tried them all, if I had to make a choice I would use Chrome.
