Yesterday, after several weeks of delay due to continued heavy crash counts, Mozilla released public beta 7 of its Firefox 4 browser, with at least three more public beta cycles planned before the end of the year. Beta 7 is the first public release to contain the device Mozilla calls JaegerMonkey, which hybridizes the optimized TraceMonkey engine introduced in Firefox 3.5 with a new just-in-time native code compiler.
The organization touted Beta 7 as being three to five times faster than the stable Firefox 3.6.12 in executing well-known benchmark suites, including the organization's new Kraken suite, and Google's V8 test battery. In a newly revised series of tests conducted this morning by Ingenus LLC, there were limited instances of 300% acceleration, but not across the board. Firefox 4 Beta 7 posted speed scores that were 2.38 times those of Firefox 3.6.12 overall.
