| 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. |

| 24 | |
| Steve Block | 8defd9f | 2010-07-08 12:39:36 +0100 | [diff] [blame] | 25 | <p>Removed dead code from the RayTrace benchmark and fixed a couple of |
| 26 | typos in the DeltaBlue implementation. Changed the Splay benchmark to |
| 27 | avoid converting the same numeric key to a string over and over again |
| 28 | and to avoid inserting and removing the same element repeatedly thus |
| 29 | increasing pressure on the memory subsystem.</p> |
| 30 | |
| 31 | <p>Furthermore, the benchmark runner was changed to run the benchmarks |
| 32 | for at least a few times to stabilize the reported numbers on slower |
| 33 | machines.</p> |

| Steve Block | a7e24c1 | 2009-10-30 11:49:00 +0000 | [diff] [blame] | 35 | <div class="subtitle"><h3>Version 5 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v5/run.html">link</a>)</h3></div> |
| 36 | |
| 37 | <p>Removed duplicate line in random seed code, and changed the name of |
| 38 | the Object.prototype.inherits function in the DeltaBlue benchmark to |
| 39 | inheritsFrom to avoid name clashes when running in Chromium with |
| 40 | extensions enabled. |
| 41 | </p> |
| 42 | |
| 43 | <div class="subtitle"><h3>Version 4 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v4/run.html">link</a>)</h3></div> |
| 44 | |
| 45 | <p>The <i>Splay</i> benchmark is a newcomer in version 4. It |
| 46 | manipulates a splay tree by adding and removing data nodes, thus |
| 47 | exercising the memory management subsystem of the JavaScript engine. |
| 48 | </p> |
| 49 | |
| 50 | <p> |
| 51 | Furthermore, all the unused parts of the Prototype library were |
| 52 | removed from the RayTrace benchmark. This does not affect the running |
| 53 | of the benchmark. |
| 54 | </p> |
| 55 | |
| 56 | |
| 57 | <div class="subtitle"><h3>Version 3 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v3/run.html">link</a>)</h3></div> |
| 58 | |
| 59 | <p>Version 3 adds a new benchmark, <i>RegExp</i>. The RegExp |
| 60 | benchmark is generated by loading 50 of the most popular pages on the |
| 61 | web and logging all regexp operations performed. Each operation is |
| 62 | given a weight that is calculated from an estimate of the popularity |
| 63 | of the pages where it occurs and the number of times it is executed |
| 64 | while loading each page. Finally the literal letters in the data are |
| 65 | encoded using ROT13 in a way that does not affect how the regexps |
| 66 | match their input. |
| 67 | </p> |
| 68 | |
| 69 | |
| 70 | <div class="subtitle"><h3>Version 2 (<a href="http://v8.googlecode.com/svn/data/benchmarks/v2/run.html">link</a>)</h3></div> |
| 71 | |
| 72 | <p>For version 2 the Crypto benchmark was fixed. Previously, the |
| 73 | decryption stage was given plaintext as input, which resulted in an |
| 74 | error. Now, the decryption stage is given the output of the |
| 75 | encryption stage as input. The result is checked against the original |
| 76 | plaintext. For this to give the correct results the crypto objects |
| 77 | are reset for each iteration of the benchmark. In addition, the size |
| 78 | of the plain text has been increased a little and the use of |
| 79 | Math.random() and new Date() to build an RNG pool has been |
| 80 | removed. </p> |
| 81 | |
| 82 | <p>Other benchmarks were fixed to do elementary verification of the |
| 83 | results of their calculations. This is to avoid accidentally |
| 84 | obtaining scores that are the result of an incorrect JavaScript engine |
| 85 | optimization.</p> |
