描述

It is important to maintain performance parity to std::span (at the very least when Safe Buffers are enabled). In order to track this, we should have performance tests between std::span and gsl::span for the latest standard library implementation across Clang, GCC, and MSVC.

@galenelias put together small benchmark comparing the two implementations on various workloads. They have been attached for convenience and provide a good starting point.

研究方向
Implement performance benchmarks comparing gsl::span to std::span, using the attached span bench.zip as a starting point. The benchmarks should measure various workloads across Clang, GCC, and MSVC. Ensure the tests are integrated into the CI pipeline so that performance regression can be tracked automatically.
