Anyone?

where is it deployed? region and deployment matters for this

is it iad1?

are you using caching techniques?

not really i dont know how

check the route at

and see which db queries that is making it slow

cache it using unstable_cache() and revalidate the data (if its updated) using revalidateTag()

you can check this in the Vercel project settings

and make sure the db location is as close as possible with the vercel's region

It's loading all these chunk files

Yes, [iad1](https://vercel.com/docs/regions#:~:text=Tokyo%2C%20Japan-,iad1,Washington%2C%20D.C.%2C%20USA,-icn1) is the region. Is it closer to your customers? make sure it is.

Also, add caching, and fix routes that are slow. Simpler solution, add a loading screen for those but load the other parts of the ui faster

My backend server is in Virgina so that should be fine

And my customers are mainly US

Is there a debugging guide of how to implement caching? I also don't understand this loading chunks issue in the screenshot above

I Dont have a guide but we can help you. Firstly id check the build log

it's so random

some time the site just wont load at all for some people

on next 14, could that be the issue?

and my local build times are so slow takes 10+ min

well thats normal with next 14

next 16 optimises build up to 70%

if u want to explore caching: start by checking build logs

then see what route slows you down

here

check such as: what db call did u have at this route? can you wrap it with unstable_cache?

You can skip it for now. Try to optimize your db calls for now. And test it with network throttling
