can benchmarks be runnable without node?

[Yaffle]

1. I have "0.00" ops/sec for all libs. Seems, "benchmark.js" does not work well under node.js for me.
2. I have no "python", so i cannot install some libs for benchmark.

It is still interesting to compare performance under web browsers.
Can the benchmark be rewritten, so it will be possible to run it under Chrome or Firefox or ... AND this will still be same benchmark?

Hm... it does work pretty well for me, what node.js version are you using?

I think it could be, with a help of browserify! Do you want to help me with this? ;)

[Yaffle]

Add next 4 lines to the index.js:

// "browserify" will set bignum to "stub"
if (typeof bignum === "object") {
  bignum = bbignum;
}

npm install browserify
browserify index.js --ignore bignum -o index.min.js
create index.html:

var console = {
  log: function (t) {
    document.body.insertAdjacentHTML("beforeend", "<br />" + t);
  }
};

setTimeout(function () {
  var script = document.createElement("script");
  script.src = "i.js";
  document.querySelector("script").parentNode.appendChild(script);
}, 10);

But
benchmark.js works very sadly for me - it takes very long time to execute, do you know how to configure it?

[indutny]

I guess benchmark.options.maxTime or something like that. It is worth noting, though, that the quality of values really depend on the time of execution.

Mind opening a PR for browserify fixes? (Or have you already done it...)

[Yaffle]

@indutny , i tried with benchmark.options.maxTime with no good result.

[indutny]

Yeah, looks like it is not enough. Try adding minSamples = 2 too.

[Yaffle]

@indutny , i tried with minSamples = 16, minSamples = 128; seems, a little better, but too long anyway.

[indutny]

Yeah, I'd suggest taking a look at benchmark source then.

[Yaffle]

@indutny , Ok, i checked with your last changes, seems it works, "create"+"create-hex" takes ~40 seconds...
But seems, "benchmark.js" works not good after "browserify", because:

1. it cannot get correct "window" object;
2. async tests are not supported, so you need to wait before any result will be displayed.

[Yaffle]

@indutny
I have to modify "index.js" a little to support "async":
