These are the parameters exposed in the Advanced Properties for The best article I can find is the below one, which does not include any tuning of parameters at all. My understanding is that we are not supposed to mess around with these parameters.

Even we can change them, I don't see a way for us to appreciate the effect of the changes.

If you suspect that you have some issues with the JFS, I suggest you contact Support.
