Nextjs RSC Payload requests are taking 3-4 seconds to load

My nextjs ecommerce site is taking 3-4 seconds to fetch the rsc payload when I navigate my website. A 55Kb RSC payload is taking 3.5 seconds, making website feel slower.

It is completely SSG except for the admin pages.

I am using Supabase as a database + auth solution.

My nextjs version: 16.2.9

I am on legacy free plan
