Look at optimizing tracing in the operators.

In looking at JSONToTuple it seems there is a lot of tracing, while they are protected with checks of the tracing level, it looks like there are two checks per atttribute when doing the conversion.

It may be that the tracing was useful during initial development, but maybe they no longer provide any value.

not valid anymore
traces with different levels in Java sources are fine.
debug traces are protected with checks of the tracing level
