> Project: IMPALA
> Issue Type: Improvement

> The codegen time measurements in profiles are often confusing because they're
> wall-clock time and can be inflated if a host is heavily loaded. We could use
> ThreadCounterMeasurement to get accurate user/sys CPU time.
> [~bikramjeet.vig] interested what you think of this since it was motivated by
> a discussion we had.
