This resolves issue 356 (http://code.google.com/p/v8/issues/detail?id=356) thanks to bitRAKE. Changed benchmark version number from 4 to 5 resulting in updates to base.js, README.txt and revisions.html. Review URL: http://codereview.chromium.org/113839 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@2058 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

The V8 benchmark suite is changed from time to time as we fix bugs or
|
|
expand the scope of the benchmarks. Here is a list of revisions, with
|
|
a description of the changes made. Note that benchmark results are
|
|
not comparable unless both results are run with the same revision of
|
|
the benchmark suite.

<div class="subtitle"><h3>Version 5 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v5/run.html">link</a>)</h3></div>
|
|
|
|
<p>Removed a duplicate line in the base random seed code.
|
|
</p>
|
|
|
|
<div class="subtitle"><h3>Version 4 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v4/run.html">link</a>)</h3></div>
|
|
|
|
<p>The <i>Splay</i> benchmark is a newcomer in version 4. It
|
|
manipulates a splay tree by adding and removing data nodes, thus
|
|
exercising the memory management subsystem of the JavaScript engine.
|
|
</p>
|
|
|
|
<p>
|
|
Furthermore, all the unused parts of the Prototype library were
|
|
removed from the RayTrace benchmark. This does not affect the running
|
|
of the benchmark.
|
|

|
|

|
<div class="subtitle"><h3>Version 3 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v3/run.html">link</a>)</h3></div>
|
|
|
|
<p>Version 3 adds a new benchmark, <i>RegExp</i>. The RegExp
|
|
benchmark is generated by loading 50 of the most popular pages on the
|
|
web and logging all regexp operations performed. Each operation is
|
|
given a weight that is calculated from an estimate of the popularity
|
|
of the pages where it occurs and the number of times it is executed
|
|
while loading each page. Finally the literal letters in the data are
|
|
encoded using ROT13 in a way that does not affect how the regexps
|
|
match their input.
|
|
</p>
|
|
|
|
|
|
<div class="subtitle"><h3>Version 2 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v2/run.html">link</a>)</h3></div>
|
|
|
|
<p>For version 2 the Crypto benchmark was fixed. Previously, the
|
|
decryption stage was given plaintext as input, which resulted in an
|
|
error. Now, the decryption stage is given the output of the
|
|
encryption stage as input. The result is checked against the original
|
|
plaintext. For this to give the correct results the crypto objects
|
|
are reset for each iteration of the benchmark. In addition, the size
|
|
of the plain text has been increased a little and the use of
|
|
Math.random() and new Date() to build an RNG pool has been
|
|
removed. </p>
|
|
|
|
<p>Other benchmarks were fixed to do elementary verification of the
|
|
results of their calculations. This is to avoid accidentally
|
|
obtaining scores that are the result of an incorrect JavaScript engine
|
|
optimization.</p>
