Hi, these are SSG/ISR pages which should be cached. However, if you see the vercel logs, the route /category/insurance goes into a serverless function and have a response time of 2s due to cold start. This should be cached on build.

Any idea?

I think I know why. I am using searchParams from the page props because there is pagination. Let me shif the pagination into client component and see how.

There are no suspense used in the page.

Once it warmed up, response dropped to 68ms

ok I changed into this format /category/insurance/2 for pagination. Looks like no more serverless function for the base page!
