Hugo's idea might be the best solution if you're dealing with that many
Reads. That is, to remove any expressions from the Reads, and instead, use a
knobChanged callback on your master NoOp to actually change the paths on the
Reads when its parameters are changed.
Expressions get evaluated a LOT, even when just moving viewer inputs around,
and string assembly expressions can be particularly heavy.
If this doesn't sound like a workable solution, can you give some more info
on what specifically would require you to use expressions?

So meen adding a knob to my read-nodes that reads a shot environment
variable to set the path..? From where should I store this variable? I want
it to be easy to update.. I guess not a Noop-node, what should I use?

We have a setup where all read-nodes get their filepath from one
Noop-node.
I'm intentionally ignoring the expression problem for now, but.. is there
anything wrong with using a shot environment variable to set the path?
Because that's what everybody does (or, seems to be doing at least).
