After about an hour of using nextjs I find the process is using over 10GB of RAM, right now it is at 13GB. It is difficult to work with. are there any configurations I might be missing? I have found memory is used when HMR occurs.

How much memory does your computer have?

#

Nextjs will use more memory on computers with more available memory, just like every other apps

#

Unless you have 16GB or less in this case, I wouldn’t worry much since it is normal

Yep, the issue is I have a team mate that has a 8GB M1 mac and is having trouble after 30 minutes.

Well… 8GB is not enough to do nextjs these days outside small apps. Source: a former 8GB MacBook Air owner

#

16GB should be enough

#

Then nextjs will take around 5-7GB depending on factors

#

Nextjs will take more when you increase the RAM available

Oh well, that is just the way it is then. Thanks
