move v8 src to google dir moving v8 source into main extension move google upstream source dir into v8 ext dir include v8 library in generated bundle prep for 0.4.7 roll the upstream build into the main extension build Documentation was confusing the gem packager. simplify build instructions with bundled v8. Only install scons and build v8 if it has not been built already. Missing CVS.py from the scons library due to ignore patterns. Don't need libv8 anymore, only python 2.5 which is required to build it.

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 duplicate line in random seed code, and changed the name of
|
|
the Object.prototype.inherits function in the DeltaBlue benchmark to
|
|
inheritsFrom to avoid name clashes when running in Chromium with
|
|
extensions enabled.
|
|
</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.
|
|
</p>
|
|
|
|
|
|
<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>
