I'm not getting very good numbers on my machine (much higher gc times than the article suggests). Perhaps it's because I'm on a mac, but it's a pretty new MacBook and safari seems to perform much better on a number of them.

Sometimes I wonder if my MacBook is even capable of employing both cores...

Came here to make the same comment. The GC benchmark has noticeable pauses on a Core 2 Duo (early 2009) MBP running 10.6. I saw figures of at least 60+ ms when the animation jerked.

safari seems to perform much better on a number of them The benchmarks on the page are mostly not intended to test relative performance across browsers other than Firefox, and almost certainly do not provide useful comparison data. They were mostly designed to exercise particular performance weaknesses in Firefox, and indicate whether those performance weaknesses are improved by the new code. Micro-benchmarks in the context of very large, complex, systems, are usually pointless...except when going after particular performance issues, as the developers of Firefox are doing.

  I've been investigating a similar disappointing performance of that benchmark on my Mac install of 3.6. Turns out that Firebug and Adblock Plus can both double the GC delay time. Trying to figure out what information to collect to report that in bugzilla right now.

    The number of hooks in Firefox seems likely to be a contributing factor in it being somewhat slower (in some regards) than Chrome and Safari, which are both extremely basic in their customizability and extensibility via third party plugins. Flexibility does usually have a cost, in software and in physical systems, and Firefox definitely goes to the extreme on flexibility. I'm about 50/50 on whether the trade is worth it, and I waffle between Chrome and Firefox as my primary browser. Firebug and AdBlock Plus are both quite demanding plugins, having to analyze and manipulate the DOM so often and in so many ways. I don't think one can expect them to have no impact on performance.
