> The capacity scheduler logs too frequently, seriously affecting performance.
> As a result of our test that the scheduling speed of capacity scheduler is difficult to reach 5000/s in the production scenario.
> And it will soon reach the log bottleneck.
> My current work is to change many log levels from INFO to DEBUG level.
