| 15 The V8 benchmark suite is changed from time to time as we fix bugs or |
| 16 expand the scope of the benchmarks. Here is a list of revisions, with |
| 17 a description of the changes made. Note that benchmark results are |
| 18 not comparable unless both results are run with the same revision of |
| 19 the benchmark suite. |

benchmarks/v3/run.html">link</a>)</h3></div> |
| 24 |
| 25 <p>Version 3 adds a new benchmark, <i>RegExp</i>. The RegExp |
| 26 benchmark is generated by loading 50 of the most popular pages on the |
| 27 web and logging all regexp operations performed. Each operation is |
| 28 given a weight that is calculated from an estimate of the popularity |
| 29 of the pages where it occurs and the number of times it is executed |
| 30 while loading each page. Finally the literal letters in the data are |
| 31 encoded using ROT13 in a way that does not affect how the regexps |
| 32 match their input. |
| 33 </p> |
| 34 |
| 35 <div class="subtitle"><h3>Version 2 (<a href="http://v8.googlecode.com/svn/data/
benchmarks/v2/run.html">link</a>)</h3></div> |
| 36 |
| 37 <p>For version 2 the crypto benchmark was fixed. Previously, the |
| 38 decryption stage was given plaintext as input, which resulted in an |
| 39 error. Now, the decryption stage is given the output of the |
| 40 encryption stage as input. The result is checked against the original |
| 41 plaintext. For this to give the correct results the crypto objects |
| 42 are reset for each iteration of the benchmark. In addition, the size |
| 43 of the plain text has been increased a little and the use of |
| 44 Math.random() and new Date() to build an RNG pool has been |
| 45 removed. </p> |
| 46 |
| 47 <p>Other benchmarks were fixed to do elementary verification of the |
| 48 results of their calculations. This is to avoid accidentally |
| 49 obtaining scores that are the result of an incorrect JavaScript engine |
| 50 optimization.</p> |
