[[Bck2Brwsr]] version 0.17 is faster. Ten years ago nobody would imagine dynamic languages could get as good performance as they have now. The feeling that [[JavaScript]] just can't be fast is presumably present in many of our souls. The truth is, it can be relatively fast - not as fast as [[Java]] as my experiment with [https://github.com/jtulach/sieve Sieve of Eratosthenes] shows, but pretty damn fast. Certainly not an excuse to be ten times slower than [[HotSpot]] (which was the previous state of [[Bck2Brwsr]]).

The daily work on [[Truffle]] compiler team and the time [[I]] got when traveling from ''Snowcamp'' at Grenoble gave me a chance to speed [[Bck2Brwsr]] up. The [https://github.com/jtulach/sieve sieve] being a nice - e.g. small and focused - benchmark. Originally the algorithm couldn't be finished in a reasonable time when running on old version of [[Bck2Brwsr]], but knowing what optimizing compilers seek for, it was relatively easy to speed it up ten times.

With great pleasure [[I]] announce that [[Bck2Brwsr]], the most complete [[Java]] [[VM]] in browser (that can run [[Javac]] as shown by [[Dew]] project) has been sped up many times being at most three times slower than [[HotSpot]]. Given the primary goal of [[Bck2Brwsr]] is [[modularity]] and not speed, [[I]] consider it a [[good]] sped up even knowing there is a room to make it even faster.
