The V8 benchmark suite
Today we have released version 6
of the V8 benchmark suite. The main changes are in the RegExp and Splay components of the benchmark suite. For reference, we describe each of the existing benchmarks in the suite below, along with any changes made in version 6.
RegExp: Regular expression benchmark generated by extracting regular expression operations from 50 of the most popular web pages. The regular expressions are exercised a number of times to reflect their popularity on those top 50 web pages. Changed in version 6: each regular expression is now exercised on a number of different input strings instead of just one.
Splay: Data manipulation benchmark that modifies a large splay tree to exercise the automatic memory management subsystem. The benchmark builds a large splay tree in a setup phase and then measures how fast nodes can be added and removed. Changed in version 6: no longer converts the same numeric key to string repeatedly and updates the splay tree in a way that increases the pressure on the memory management subsystem.
Crypto: Encryption and decryption benchmark based on code by Tom Wu. The benchmark encrypts an input string, decrypts the result and verifies that encryption followed by decryption yields the original input. The encryption/decryption algorithm is RSA and the benchmark measures the performance of arithmetic operations on integers and array access.
