Describe the bug

I have all the caching functionality enabled but ttfb still ranges from 1.2s to almost 3 seconds!

Most of my pages are staticky rendered. My landing page reads the 'CF-IPCountry' header to localise pricing to the customers IP address. I don't have any middleware

CPU & wal times vary massively (i'd assume some pages need to be rendered, others can be pulled from cache?)

Unfortunately this makes this library almost completely un usable for almost all websites.

Am I doing something wrong? 3 seconds TTFB will cause customers to stop navigating to the site.

Steps to reproduce

Almost any @opennextjs/cloudflare deployment.

Expected behavior

Pages not to take 1-3 seconds to send first byte.

@opennextjs/cloudflare version

1.0.1

Wrangler version

^4.14.1

Additional context

open-next.config.ts:

import { defineCloudflareConfig } from "@opennextjs/cloudflare";
import doQueue from "@opennextjs/cloudflare/overrides/queue/do-queue";
import kvIncrementalCache from "@opennextjs/cloudflare/overrides/incremental-cache/kv-incremental-cache";

export default defineCloudflareConfig({
  queue: doQueue,
  enableCacheInterception: true,
  incrementalCache: kvIncrementalCache,
});

the https://vercel-commerce-on-workers.web-experiments.workers.dev/ deployment's TTFB seems to range from 500-800ms which is much more reasonable. Is anyone able to link to its repo so I can compare my configs/versions? I can't find it.
