Why Emacs Consult async searches feel slow and how to speed them up? (consult-fd, consult-find, consult-grep, consult-ripgrep...)

The consult Emacs package provides asynchronous search commands such as consult-fd, consult-find, consult-grep, consult-git-grep, and consult-ripgrep.
For these commands, Consult does not necessarily start a new search for every change to the minibuffer input.
Instead, it uses configurable debounce and throttle delays to control when asynchronous processes start, while a separate refresh delay controls how frequently asynchronous results are pushed to the completion UI.
