# V8 Benchmark Suite - version ?

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: Bigger is better!

- Richards
  OS kernel simulation benchmark, originally written in BCPL by Martin Richards (539 lines).
- DeltaBlue
  One-way constraint solver, originally written in Smalltalk by John Maloney and Mario Wolczko (880 lines).
- Crypto
  Encryption and decryption benchmark based on code by Tom Wu (1689 lines).
- RayTrace
  Ray tracer benchmark based on code by Adam Burmister (3418 lines).
- EarleyBoyer
  Classic Scheme benchmarks, translated to JavaScript by Florian Loitsch's Scheme2Js compiler (4682 lines).
- RegExp
  Regular expression benchmark generated by extracting regular expression operations from 50 of the most popular web pages (4758 lines).

Note that benchmark results are not comparable unless both results are run with the same revision of the benchmark suite. We will be making revisions from time to time in order to fix bugs or expand the scope of the benchmark suite. For previous revisions and the change log see the revisions page.
