Drastic improvements indeed, but still far from the fastest. I prefer FF, but the gap in performance is too large to ignore compared to chrome on mac.
So I read this article Chrome has gotten 26 percent faster this year , and wondered how fast has FF become over a year !
I ran the same Octane test , for FF8 , FF16 and the latest nightly FF 19 (The build is exactly a year after FF 8 was launched).
The results were :
FF 19 6025 (106%) <8 Nov 2012>
FF 16 5408 (85%) <9 Oct 2012>
FF 8 2921 (0%) <8 Nov 2011>
So that's all , FF has seen such drastic performance improvements over a year that it puts Chrome's improvements to dust.
Just for sake of comparison , I also tested Chrome 24.0.1312.5 dev , and it scored 8577 (42% faster than FF 19) , which ain't that bad I guess for Firefox I guess.
PS : A very delightful and a happy birthday to Firefox for completing its 8 years !
