Can SPECweb99 results be meaningfully compared to SPECweb96 results?
No. Although the benchmarks are similar, they cannot be compared, since SPECweb99 uses an entirely different metric than SPECweb96. SPECweb99 also has different file access distributions and a mix of different types of server queries. The dynamic part of the SPECweb99 workload has no SPECweb96 equivalent, so there is no way to make meaningful comparisons between the two.
