I would suggest to only optimize anything when it is [needed](https://www.laws-of-software.com/laws/knuth/) (either because of performance issues, or because the current system is hard to work with).

If your server can deal with the current architecture and there is enough network bandwidth, I would not complicate my life with manual data synchronization, global variables, single network call, etc., because the end results seems much harder to work with and easier to mess up / introduce bugs.

But since you mentioned each machine has a dedicated flow, I would rather try to simplify that (just like in programming: [DRY principle](https://en.wikipedia.org/wiki/Don't_repeat_yourself)) and implement the generic flow only once and call it with different parameters via link in/out+call nodes.

Also don't forget to set the default context to [persistent file storage.](https://discourse.nodered.org/t/a-guide-to-understanding-persistent-context/4115)
