Kill ring performance problem

[drorbrillsnps]

In some cases getting clipboard content can take a very long time (nothing to do with Emacs+ plugin).
Because the Kill ring feature in Emacs+ reads clipboard content even when the user did not activate a "paste" command, sometimes it can cause long freezes (see example below), even though the user did not attempt to use the "paste" command.

Is there a way to disable the Kill ring feature entirely?
Is there a way to reduce or avoid getting clipboard content unless the user actively wants to get content from it?
