Zhu Zhu commented on FLINK-27555:
---------------------------------
This benchmark result is how much time it takes to do the scheduling.
Therefore, it is actually an improvement instead of a regression.
The improvement is caused by FLINK-27460 which removed some logics which are no
longer needed.
I can see it is the description on the left of the dashboard that is causing
the confusion.
But I'm not sure whether there is a way to change the description for certain
benchmarks to clearly show that it is "Time cost (less is better)".
