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). + + +Changes From Version 1 To 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. + + +Changes From Version 2 To Version 3 +=================================== + +Version 3 adds a new benchmark, RegExp. The RegExp benchmark is +generated by loading 50 of the most popular pages on the web and +logging all regexp operations performed. Each operation is given a +weight that is calculated from an estimate of the popularity of the +pages where it occurs and the number of times it is executed while +loading each page. Finally the literal letters in the data are +encoded using ROT13 in a way that does not affect how the regexps +match their input. |
