Sometimes it gets so bad I have to reload vscode entirely.

you can try the turbopack, but it can be more buffy (so far on projects thata it works on for me, it uses less mem and is faster)

what's that?

in your package.json, change the dev script

i just get this:

[node.js fs] rename failed after 489 retries with error: Error: EPERM: operation not permitted, rename 'C:\Users\[user]\OneDrive\Documents\Workspace\ramen\.next\server\middleware-build-manifest.js.tmp.0qt8sycg78v' -> 'C:\Users\[user]\OneDrive\Documents\Workspace\ramen\.next\server\middleware-build-manifest.js'

}

try removing the ./.next folder

doesnt happen without --turbo

any help?

turbo is indeed buggy

so uhh lets forget that option if your libs dont work with it

what are your specs of device

i have 16gb ram and it works decently

do you have 4 or something low and thus cant spare much on dev server

i have 40gb of ram and an intel i7

oh thats so good

yeah uhh thats sad if it makes it laggy and unusable

it only uses like 1gb of ram (even outside vscode) but it hogs the cpu

It gives this one createContext error that makes me restart the dev server sometimes

and it memory leaked like twice

Yeah I don’t trust it right now

Anyway is there anyway to make next dev faster or am I stuck?

maybe don't save your projects within onedrive? lol

I dont use onedrive. The folder is left over and I was too lazy to move everything (still am)

Shit... try running it on a M1 macbook. I'm working on a pretty large app, that by it's very nature has to dynamically import just about everything and then only actually ship what is needed, but because Next has to load all of those dynamic imports on the server, the development server is completely unusable. I'm moving everything over to a monorepo right now so I can accomplish literally anything... and it's a nightmare.

Glad I’m not the only one

I hope something is done soon to make it faster cause it’s pretty bad rn

next dev has memory leaked on me way too many times

This is really a problem- my laptop isn’t very high-end and it constantly overheats because of this.

My desktop handles it ok after a while but my laptop can’t handle it

I have made this a discussion on github as well https://github.com/vercel/next.js/discussions/63068#discussion-6343320
