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.

<p>This version includes the new Navier-Stokes benchmark, a 2D differential

equation solver that stresses arithmetic computations on double arrays.</p>

<p>Removed dead code from the RayTrace benchmark and fixed a couple of
|
|
|
|
|
typos in the DeltaBlue implementation. Changed the Splay benchmark to
|
|
|
|
|
avoid converting the same numeric key to a string over and over again
|
|
|
|
|
and to avoid inserting and removing the same element repeatedly thus
|
2010-10-01 23:18:59 +02:00
|
|
|
increasing pressure on the memory subsystem. Changed the RegExp
|
|
|
|
|
benchmark to exercise the regular expression engine on different input
|
|
|
|
|
strings.</p>
|
2010-07-03 08:36:33 +02:00
|
|
|
|
|
|
|
|
<p>Furthermore, the benchmark runner was changed to run the benchmarks
|
|
|
|
|
for at least a few times to stabilize the reported numbers on slower
|
|
|
|
|
machines.</p>

|
|
|
|
the Object.prototype.inherits function in the DeltaBlue benchmark to

<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>
|
|
|
|
|
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>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.

<div class="subtitle"><h3>Version 2 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v2/run.html">link</a>)</h3></div>

|
|
|
|
|
2009-06-08 18:34:06 +02:00
|
|
|
<p>For version 2 the Crypto benchmark was fixed. Previously, the
|
2009-04-22 19:35:47 +02:00
|
|
|
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>
