@subgum: if you're a web developer, then you'll know the scripting language used is not 'Java', but 'Javascript' (an implementation of ECMAscript, currently at version 5).
Douglas Crockford is a reference in the Javascript world: he's written reference books on it, probably forgotten more about JS than you'll ever learn (or I for that matter) and his JSlint tool is incredibly useful for removing useless code, ensuring maximum compatibility and increasing reliability before compression.
My own personal tests show that indeed, Chrome is flakey depending on the JS scenario: it can be very fast (typically on Google apps) or very slow (on 3rd-party apps).
Please note that apart from Firefox, JS speed has no bearing on how fast a browser opens (I'm singling out Fx because it uses JS, among others, to draw its own interface).
