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).

Revisions of the benchmark suite

Please 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.

Version 1

Initial release.

Version 2

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.

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.
