Minefield Shows the (Really) Fast Future of Firefox 412

Posted by timothy from the zipping-right-along dept.
zootropole writes "If you are using Firefox 3 (or even Chrome) you should consider taking a look at Mozilla's Minefield. This browser (alpha version yet, but stable) would give a new meaning to 'fast browsing experience.' Some Firefox extensions aren't supported, but riding the fastest javascript engine on the planet definitely worth a try. Minefield's install won't affect your Firefox, so there's no risk trying it. It's fast. Really. And I'm loving it." Reviews popping up around the web are overwhelmingly positive, calling the upcoming browser crazy fast, blisteringly fast, etc.

          You missed out the 'or' operator. The original statement was that IF (you want to use extensions OR you want to avoid crashes) THEN you shouldn't use nightlies. The followup said that he used the nightlies and avoided crashes just as well as with the stable release, although he didn't use extensions. So: wants to use extensions FALSE, wants to avoid crashes TRUE, and as it turns out nightlies work just fine. Hence OP's theorem is disproved by counterexample.

      What's more, this is the same thing we hear every 2 years. "Browser X is really fast!" Then six months later you hear, "Browser X was lagging behind the pack because it didn't have support for A, B and C, but now it's getting them." After that you get, "Why is Browser X so slow these days?" And inevitably, "Browser Y is really fast!"

      When are we going to realize that browser maturity and performance are going to be on opposing curves and jumping ship to an immature browser just sets you up to lose functionality for a short period of time until the performance can be gobbled up by it.

      This is exactly why I'm not using Chrome. Chrome is very nice, but it doesn't have most of what I require of a browsing experience. Once it does, THEN I'll evaluate its competitiveness, not before.

        Speed seems to be determined by a lack of bloat... and by bloat, I mean features. Firefox, back in the days it was referred to as phoenix, was exceedingly fast. Since then, fancy bookmarking, spellchecking, rss feeds, etc, etc has been added to it, causing slow startup and loading times. With the addition of a few thousand lines of code, not surprisingly, anything will take a bit longer to start up and go.

        Chrome doesn't have many features, so it runs amazingly fast. Minefield doesn't have many features, so it runs amazingly fast. If either of them are weighted down with features (code bloat) then they will slowly grind to a halt much along the lines of IE or current FF.

      Minefield (jit enabled): 1412.4ms
      WebKit: 680.6ms

      FF3.0.3 - 199 runs
      Minefield (jit enabled): FAIL (brings up printer dialog rather than actually running javascript)
      WebKit: 2342 runs

      FF3.0.3 - 71 and significant laggyness
      Minefield (jit enabled): 89 with only a little jitteryness

      Of course, you have to enable the TraceMonkey JIT JavaScript compiler before you'll see any reasonable speed increase (in theory). Just go to about:config, search for the 2 items with "JIT" in their name, and enable them.

      My stress tests have shown it to be 10-50% faster than Chrome *when* JIT works. However, it's still buggy as hell, it eats its own memory heap and grinds to inexplicable halts kinda randomly whenever my code does anything repetitive and strenuous, bringing the average execution speed down to almost FF2 levels, meaning it's faster for me to leave JIT disabled. It's a no-go for me until they fix that.

      People are talking as if Chrome's V8 was the fastest JavaScript engine around, but it wasn't - WebKit's SquirrelFish Extreme was faster [slashdot.org]. Is Minefield's engine even faster? Ars Technica's tests [arstechnica.com] show that TraceMonkey runs the SunSpider benchmark in between 78% and 84% of V8's time. However, according to earlier tests [blogspot.com], SquirelFish Extreme completes the benchmark in 74% of V8's time, making it even faster than the newest TraceMonkey. So it looks like Minefield, though fast, is not the fastest browser in JavaScript.

        I'm interested in using Javascript as an embedded language, it's too bad most of the current JS engines assume they will be running in a browser. Yes, you can build standalone TraceMonkey and SquirrelFish shells but it isn't very easy on all platforms (no Visual Studio project, etc) and they aren't very easy to embed.

        For general application development outside of a browser I have found V8 to be faster than the others. It's also a lot easier to build standalone or embedded in other applications. It's also very easy to add extensions to (written in C++), especially compared to the other choice.

        I'm keeping my eye out but right now V8 fits my needs the best. If the other projects would do a little work towards focusing on general application development in their respective JS engine then I might switch. Switching will be a pain in the butt though because my C/C++ extensions will have to be ported to each engine. I kind of wish there was less diversity because right now it's hard to tell which engine is going to take off (eg. Google could abandon V8 for one of the other engines like SquirrelFish since they are using WebKit anyway).

        Unfortunately all of them, including V8, are pretty large compared to cleaner scripting languages like Lua which makes embedding them in mobile applications kind of annoying (although we're getting more and more space on these things).

        These benchmark results are a bit debatable - I've seen different suites electing different "winners" and, while SunSpider seems to be the best, it's a long way from a robust benchmark like SPEC* or DaCapo.

        In any event, even if SFX is leading the pack right now, that's because it's the most mature competitor, and its advantage won't last too long. I predict (and I write this logged with my account, not AC, so I would be forever glorified when this becomes true in 12 months max) that both V8 and TraceMonkey will take the lead, leaving SFX in a safe third place permanently.

        The reason is very simple. All these new JS VMs are JIT compilers, producing native code. But SFX is a context threaded JIT [ualberta.ca]. Context threading is just a step beyond traditional direct-threaded interpreters: functions are 'compiled' into streams of CALLs into routines that implement each bytecode operation, but there is limited inlining (simple operations and branches), with a focus on reducing branch misprediction.

        OTOH, both V8 and TraceMonkey are "real compilers" that emit real native code (not CALL streams) for entire functions (or even larger chunks of code, with inlining). This is necessary to enable traditional optimizations like register allocation, instruction scheduling, constant folding, loop unrolling etc. Some of these optimizations can be performed on a high-level intermediate code representation (HIR), but that's typically not worth the effort without real compilation. E.g., loop unrolling will just waste memory an i-cache efficiency if performed by a threaded interpreter/JIT... as the real benefit of unrolling is giving the compiler a much larger basic block to perform other opts like extra folding and bounds-check elimination, or real low-level tricks like exploring using SIMD registers and operations / Instruction-Level Parallelism / prefetching / branch predication etc.

        The only reason why V8 and TraceMonkey don't completely 0wn the benchmarks today, is that these JITs are still in their infancy. They have implemented the foundations (like V8's hidden classes or TM's tracing), but they still miss to implement dozens of important optimizations (including very easy ones - they just didn't have the time yet). Check some comments about V8's limitations [google.com]. TM's developers have also commented on many limitations, quote (Andreas Gal: "If it talks to the DOM during the benchmark, we currently donâ(TM)t compile across such calls (we plan to for Beta2 though)". This and several other improvements are planned for future builds of Firefox 3.1 [mozilla.org]. Notice that items like special support for DOM interactions and event handlers should be critical to some benchmarks - and of course to real-world RIA apps. I'm sure the V8 hackers are also working around the clock to fill in their own gaps. When both VMs are reasonably mature, SFX will have a VERY hard time competing (unless of course, they abandon the context threading model and mutate into a real compiler). Other optimizations, like JITted regex, can be implemented in all VMs and will eventually be ubiquitous.
