Chrome’s Java engine is being engineered to deliver even greater performance than Chrome is already known for. In this article “How Google is Making Chrome Faster and Smoother” it’s explained how Google is going about this. Chrome is already considered the fastest browser so it will be interesting to see what more they can eek out of it.
Personally, I find little difference in speed perception between the three major browsers so I base my choice on which one I prefer to use. After years of solely using Safari, I’m now using Firefox as I like the way it operates.
