[LAU] Why is Jack so slow?

I have a Raspberry PI with a PI Sound board. Wanting to use modep
(https://blokas.io/modep/) live I have hacked a pedal together and can
change settings with it.
modep is a gnarly ball of python and tomahawk (sp?) that I do not need
so I have stripped down the actions the pedal needs to do to eight Jack
operations: disconnect the left and right output and input, and
reconnect them in a different way to affect an effect change.
I have written a small rust programme with the jack crate to interface
with Jack. Four disconnects, four connects.
It takes over 200ms of system time, optimised rust. Two hundred
milliseconds is a long time.
Can anybody tell me why? Is there a solution?
I am hoping to get it down to ten milliseconds.
If not me then who? If not now then when? If not here then where?
So, here I stand, I can do no other
