PerformanceTests/SunSpider/TODO

* Add more test cases. Categories we'd like to cover (with reasonably
  real-world tests, preferably not microbenchmarks) include:

  (X marks the ones that are fairly well covered now).

    X math (general)
    X bitops
    X 3-d (the math bits)
    - crypto / encoding
    X string processing
    - regexps
    - date processing
    - array processing
    - control flow
    - function calls / recursion
    - object access (unclear if it is possible to make a realistic 
      benchmark that isolates this)

  I'd specifically like to add all the computer language shootout
  tests that Mozilla is using.

* Normalize tests. Most of the test cases available have a repeat
  count of some sort, so the time they take can be tuned. The tests
  should be tuned so that each category contributes about the same
  total, and so each test in each category contributes about the same
  amount. The question is, what implementation should be the baseline?
  My current thought is to either pick some specific browser on a
  specific platform (IE 7 or Firefox 2 perhaps), or try to target the
  average that some set of same-generation release browsers get on
  each test. The latter is more work. IE7 is probably a reasonable
  normalization target since it is the latest version of the most
  popular browser, so results on this benchmark will tell you how much
  you have to gain or lose by using a different browser.

* Instead of using the standard error, the correct way to calculate
  a 95% confidence interval for a small sample is the t-test. 
  <http://en.wikipedia.org/wiki/Student%27s_t-test>. Basically this involves
  using values from a 2-tailed t-distribution table instead of 1.96 to
  multiply by the error function, a table is available at
  <http://www.medcalc.be/manual/t-distribution.php>

* Add support to compare two different engines (or two builds of the
  same engine) interleaved.

* Add support to compare two existing sets of saved results.

* Allow repeat count to be controlled from the browser-hosted version
  and the WebKitTools wrapper script.

* Add support to run only a subset of the tests (both command-line and
  web versions).

* Add a profile mode for the command-line version that runs the tests
  repeatedly in the same command-line interpreter instance, for ease
  of profiling.

* Make the browser-hosted version prettier, both in general design and
  maybe using bar graphs for the output.

* Make it possible to track change over time and generate a graph per
  result showing result and error bar for each version.

* Hook up to automated testing / buildbot infrastructure.

* Possibly... add the ability to download iBench from its original
  server, pull out the JS test content, preprocess it, and add it as a
  category to the benchmark.

* Profit.
