App Store download stats

On June 17 to June 18 last year, Mozilla set a new world record for most number of downloads in a 24 hour period for Firefox.

According to stats supplied by Apple and as reported by AppleInsider:

#####

Since it first opened 445 days ago, the App Store has seen an average of 4.5 million downloads per day. In the last 80 days alone, that total has accelerated to nearly 6.3 million each day.

For comparison, in its first 365 days, the store had an average 4.1 million downloads per day. From April to July 2009, that pace increased to 6.3 million each day.

#####

If this growth rate continues, by the end of 4th quarter 2009 App Store downloads will exceed the world record set ON A DAILY BASIS.

Webkit r47948 with Snow Leopard SunSpider Benchmarks

Last year October WebKit was the undisputed leader when it came to running the SunSpider benchmark. How does it compare with the latest nightly build of WebKit under Snow Leopard?

So, with all hardware remaining the same, the only changes are Snow Leopard and the WebKit build. I've gone from 745ms to 411.6ms. That's a speed bump of 1.8x. Not bad at all!
