Safari 3.1 has been released, bringing with it all the latest and great Webkit code. Even though the UI still sucks (at least on Windows; ever hear of native GUIs, Apple?)
I decided to benchmark the Javascript performance of the new Safari against its more immediate predecessor, 3.04. This testing was done on a Windows XP SP2 installation; a HP workstation with a Pentium 4 and 2GB of RAM.
As you can see in the table below, the JS engine has improved considerably since the last build, cutting the total time by more than half.
