But it seems faster. Everything seems faster. New iPhone OS releases always seem faster, new point releases of OS X seem faster, new stuff just seems faster. So I decided to spend most of my day trying to quantify this seemingly faster build.

Here’s what I got.

Dromaeo
Mozilla JavaScript performance test suite. I ran ALL tests, which takes about 30 mins, so I have one result per browser. The nightly wins by .5%!!

Bigger Numbers Are Better

SunSpider
I ran this three times for each browser and took the average. The beetle build wins by 2%!!

Smaller Numbers Are Better

V8 Benchmark Suite – Version 5
Ran this three times and took the average. The beetle build wins by 5%!!

Peacekeeper
Some cheez generic browser benchmark site. Never heard of it. Ran the test three times and took the average. Firefox nightly wins by 3%!!

Tab Loading
Here is where the seeming speed gets put to the test. Loaded a cross section of 25 sites in 25 tabs. Used the ol’ iPhone stopwatch, ran three times from a warm launch and took the average.

Well, look at that. The beetle build whomps Firefox by over 30%!!

Yes, the nightlies might be better. I’m pretty sure they’re more stable, I’m positive they’ll at least load Flash, and they’re probably even better optimized for your machine. My builds are optimized for myself, more tuned for 10.6.x and 64-bit so I’m going after the bleeding edge.

Oh yeah, here’s the Firefox nightly and the beetle build used in these tests.

Because of these issues and the fact that I’ve been working on a project that requires a massive number of open tabs, I’ve moved to Camino. If you don’t know about Camino, go check it out. It’s a lightweight, cocoa browser with the Gecko 1.9.x rendering engine. And it kicks Firefox’s ass! There are a lot of things missing, but what you gain is speed. (Also, there are a ton of little things like being able to tab through links on a page).

I’ve been using the 2.0 Beta 3 release for a while and decided to push things a bit. Although Camino is already pretty well optimized for the Mac, I applied my Firefox build knowledge to try to take it further. While the JavaScript benchmarks are almost identical between my build and the official build, the overall browser experience seems to be faster. I know this is very subjective and means nothing, but the perceived difference is real for me.

So, I’m releasing an Intel-Optimized build on my downloads page. In the next week, I’ll upload my .mozconfig for Camino to see if there are further tweaks the community can point me to. For now, I just want to get the binary out there and some feedback.

So, comments please…

Shiretoko

Update: Shiretoko 3.1b4pre is now available, some new numbers and a slightly updated FAQ.

BeatnikPad has been offering G4/G5/Intel optimized builds of Firefox 3.0.x and earlier for a number of years now and I’ve grown somewhat reliant on them. This has been a great service to the Mac community and I really appreciate all of Neil’s efforts. He is not only timely with the builds, but is very good with user support as you can see in his comments.

I’ve been using WebKit, Minefield, and increasingly Opera as my main browsers for a while now (and Bon Echo (Firefox 2)) and have recently been running Shiretoko (Firefox 3.1) to take advantage of TraceMonkey. But I’ve been longing for an Intel optimized build and haven’t found one, so I’ve made one.

Shiretoko 3.1b3pre had a SunSpider JavaScript Benchmark of 1333 and Shiretoko 3.1b4pre clocks in at 1449. The regex engine is vastly improved, while 3d/access/math took a hit. I think I can optimize further with the browser config, but don’t have time at the moment.

I’ve also made a few adjustments to the default config, namely turning on TraceMonkey and other minor tweaks to eek some additional speed out.

Mini FAQ

What’s the deal with all these weird names?
Non-official builds cannot use Firefox branding. I guess I could call it something else, but everyone in the dev community knows this particular version as Shiretoko.

Is Shiretoko Japanese for something?
Yes. Since dev builds are named after parks and this one is named after the Shiretoko National Park in northern Japan. (thanks Mike).

Is this going to break my existing Firefox?
No. You just cannot run them simultaneously.

Will my add-ons work?
Maybe. Firebug works and that’s all that matters to me.

Will you be doing nightly builds?
Yes. Since there is the demand for it, I will start nightlies once my current data crunching project is finished (I cannot interrupt this project every night). I expect to have this done by the end of March.

Will you build for different architectures?
No. Intel is where it’s at.
