+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).
+
+
+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.
