V8 Benchmark Suite | ||
================== | ||
|
||
This is the V8 benchmark suite: A collection of pure JavaScript | ||
benchmarks that we have used to tune V8. The licenses for the | ||
individual benchmarks are included in the JavaScript files. | ||
|
||
In addition to the benchmarks, the suite consists of the benchmark | ||
framework (base.js), which must be loaded before any of the individual | ||
benchmark files, and two benchmark runners: An HTML version (run.html) | ||
and a standalone JavaScript version (run.js). |
