Tips for working with rtags

[Nidish96]

Firstly, great job! I just love this package - working from emacs has never felt cooler + more productive 👍

But as I have started using, I have realised that rtags has started lagging (sometime waaaay too long). I once tried to delete all the cache files (in ~/.cache/rtags/) and then regenerated them, and it was very fast again. As I start building my code, I've noticed that it starts lagging and performance issues start coming up.
I want to know if this is a problem specific to only me, in which case I'd like to find out what I'm doing wrong, or if it's a more commonly encountered problem. I'd like to know, from other users, if the ide system performs as fast as it should always.
Are there any particular tips for working with rtags? (for eg this link mentions that we should not be saving too often) It is very hard to find such a thread online. I would appreciate it if some useful tips could be shared.

PS: I am currently working on a project with 2-3 branches - will this affect the tags created ? Like some tags created for one branch may be irrelevant for another.

I've never had that problem personally myself and I was editing a fairly large project.

Not a query; just leaving an observation
I just figured that using flyspell slows down the go-to-declaration features of rtags horribly! I just disabled it and performance is much better than before.
