PragmaTwice opened a new issue, #563:
URL: https://github.com/apache/incubator-kvrocks/issues/563

   The `-O0` option currently added to target `kvrocks` in 
[CMakeLists.txt](https://github.com/apache/incubator-kvrocks/blob/unstable/CMakeLists.txt#L85)
 is confusing, as it may prevent compilation optimizations in Release mode.
   
   The performance impact of compile optimizations can be huge, especially with 
heavy use of the c++ standard library, where optimized versions can be tens of 
times faster than unoptimized versions.
   
   Were there any special considerations for adding `-O0` at that time?
