Thank you for your time.

In what version are you on? The latest versions break down the dev server time and your app's code time:

 PUT /api/sandbox/shared 200 in 329ms (compile: 1842µs, render: 327ms)

There for example I am doing some heavy rendering stuff (on purpose) with a remote sandbox - you can see, the compile was like 1-2ms and then I had to do a bunch of roundtrips to get the sandbox to do something and collect the result.

Obviously kind of joking here. But yeah im on the latest atm. Rsc's causing havoc during dev, from infinite rerenders to unresponsive hmr. Having to restart it constantly. It's all so frustrating.

Got some example? Is it also slow to compile? Infinite re-renders I've heard before, with various solutions, just recently someone mentioned that somehow deleting some MacOs cache fixed it for them. That's generally a problem here, is that there's a lot of anecdotes, very few actual repositories where one could repro and fix issues 🙃 - there's still more coming though, incremental cache for dev mode and other boosts

Is it Turbopack you are using?

[jim-spr]

Yes turbopack. I've had some help from Neutkens before to see what can be done. And back then barrel files was the main issue (webpack). But as my project has grown, it's becoming more and more slow in dev. I removed all barrel files, took out most of the scss modules, have removed iconpacks that were not shakeable. Tried almost everything, it's not easy to reproduce for me because it's a pretty big project for me at least. And is live atm. Basicly anytime I make a chance on the server side, I see the dev server go in almost infinite loop doing rsc requests. And then suddenly breaks out and renders the page. I even removed all parallel routes because they seemed to be pretty unstable and triggered them more often. But im sick of jumping through endless hoops trying to see improvement. Half my day im fighting the dev server, not exaggerating. Im very much looking forward to the improvements!
