WorkOS is a modern identity platform for B2B SaaS, supporting SSO, SCIM, user management, and RBAC.
There are lies, damn lies, and benchmarks, but InfoWorld’s Tom Yager thinks Apple’s new benchmarks are especially bogus:
In short, Apple used multiprocessor benchmarks to skew the performance advantage that its Intel-based machines enjoy compared to single-core PowerPC G4 and G5. Apple used the industry-standard SPEC suite components SPECint2000 and SPECfp2000, but here’s the catch: Apple used SPECint_rate2000 and SPECfp_rate2000. Both tests spawn multiple parallel benchmark processes and are specifically intended for comparing multiprocessor systems. Single CPU, or single-core machines do positively lousy on SPEC*_rate2000 tests. That’s predictable and universally understood. […]
Apple uses SPEC*_rate2000 tests as a foundation for claims that Intel-based Macs outperform PowerPC G4 and G5 by a factor of 2 to 5. Well, yeah. A dual-core anything outperforms a single-core anything else by a factor of 2 to 5 in benchmark tests that make use of multiple threads or processes, tests crafted specifically for the purpose of stressing SMP-based systems.
