This page contains a suite of pure JavaScript benchmarks that we have
|
|
|
|
|
used to tune V8. The final score is computed as the geometric mean of
|
|
|
|
|
the individual results to make it independent of the running times of
|
|
|
|
|
the individual benchmarks and of a reference system (score
|
|
|
|
|
100). Scores are not comparable across benchmark suite versions and
|
|
|
|
|
higher scores means better performance: <em>Bigger is better!</em>

|
|
<p>Initial release.</p>

<div class="title"><h3>Version 2</h3></div>

2008-10-02 07:43:46 +00:00
|
|
|
<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>
