I much prefer Bing over Google simply because Google strikes me as the most aggressive harvester/seller of personal data. So I downloaded the Bing App yesterday. It is a gorgeous app that I enjoy quite a bit more than Safari or Chrome.
So here's the rub. While using the Bing browser it immediately struck me as a bit slower than Safari. I wondered if I was imagining this or if it was real. So I visited the Sunspider web site and ran their browser benchmark. My iPad running 5.1 iOS pulled a 10,139. I than ran the benchmark on Safari and pulled a 2,905. WOW! Over three times faster. Out of curiousity, I pulled up Google Chrome and Sunspider came in at 9,255. Faster than Bing, but still waaayyyy slower than Safari.
I suppose these results are not unexpected considering the considerable advantage that Safari must have over 3rd party browsers. But I am surprised at how large the gap is.
