Missing information

I recently was asked about the difference between the 4 alternative values for "Cache Settings" found on the tab labeled "Performance" in the AX Configuration Utility (client) - se example below.

The different options are explained directly in the GUI, but I would like to know how this mechanism is implemented (technically). I have searched all possible sources (formal and informal) without finding any information at all. It's not unusual to hit "blind spots" like this regarding formal documentation around Dynamics AX, but it should not be necessary to open a support case every time this happens.

Anyone having a reference or are willing to share some experience regarding the effect of this setting?
