Explanation

HDF5 performance benchmark suite is available for regular performance testing of HDF5. There are a number of useful ways to expand HDF5 perf:

• Add parallel I/O performance tests (a tool h5perf currently tests HDF5 parallel I/O);
• document MPE
• Implement performance regression testing
• Add more criteria for the benchmark (currently only time is used. We could add file size, overhead, for instance)
• Add more sequential benchmarks into the framework
