• -o support rename the output
• -cmp Benchmark1 Benchmark2 compare benchmarks with different names
• Do not save benchmark results until we have enough data (improve error messages)
• Better support macOS with performance locking (@yangwenmai)
  • On Linux we have great stuff: https://www.kernel.org/doc/Documentation/cpu-freq/governors.txt
  • How to control cpureq on darwin? Here are some investigations, needs a double check:
  • sysctl hw | grep freq
