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 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.
|
||
|
|

|

|
<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>
