Why is my Next.js app slow in production but fast locally?
Is Next.js 16 cache actually working with dynamic pages?
What’s the actual difference between Redis cache and Next.js cache?
What’s the actual difference between Zustand and React Query?

I'm trying the new cache system in Next.js 16 App Router ("use cache", cacheTag, updateTag, etc.) and honestly I'm not sure if caching is actually stable yet with dynamic pages and searchParams.
Sometimes it works. Sometimes navigating between query params keeps stale UI. Sometimes Suspense fallback doesn't trigger. Sometimes invalidation works only after refresh.

I had the same confusion with Next.js caching.
The docs explain the APIs separately, but real apps combine:

The docs are good for reference, but understanding caching properly really takes experimentation.
