Even without a flash miner the mining performance could be increased by up to 1000% by using a more clever js algorithm.
I've got a proof of concept running here at 26khash/s vs. ~2.6khash/s that bitp.it currently gets in FF4, similar results in other browsers.
would you mind publishing that poc or at least tell us where it's from?
none of the sha256 implementations i've seen so far were able to reach 10x times more than the jsminer of bitp.it . the best i've seen so far was ~twice the hash power
2x? 10x? no, 20x!
Just got 50KHash/s in Firefox 4.0.1, DOM worker mode on a Core i7 620M. The bitp.it frontpage gets like 2.3KHash/s.
Firefox 4.0.1, DOM worker: 50KHash/s
Firefox 4.0.1, UI thread: 20KHash/s (but only 15% CPU load due to 30 milliseconds of delay after every 1024 hashes)
IE 9.0.8112.16421, DOM worker: 13KHash/s (possibly no DOM worker support, so falling back to UI thread?)
IE 9.0.8112.16421, UI thread: 13KHash/s
Chrome 13.0.742.91, DOM worker: 12-81KHash/s (swinging badly, no idea why)
Chrome 13.0.742.91, UI thread: 9KHash/s
So every single result is better than what bitp.it currently gets, and Firefox even gets 2000% performance consistently!
