SPEC Benchmark Suites
The benchmarks aim to test "real-life" situations. There are several benchmarks testing Java scenarios, from simple computation (SPECjbb) to a full system with Java EE, database, disk, and network (SPECjEnterprise).
The SPEC CPU suites test CPU performance by measuring the run time of several programs such as the compiler gcc, the chemistry program gamess, and the weather program WRF. The various tasks are equally weighted; no attempt is made to weight them based on their perceived importance. An overall score is based on a geometric mean.
