Slow cold start and latency for hello world code

Hi, I have a simple worker, deployed recently. The content is a simple hello world provided by the Cloudflare dashboard, the code is the below:

export default {
  async fetch(request, env, ctx) {
    return new Response('Hello World!');
  },
};

export default {
  async fetch(request, env, ctx) {
    return new Response('Hello World!');
  },
};

export default {
  async fetch(request, env, ctx) {
    return new Response('Hello World!');
  },
};

export default {
  async fetch(request, env, ctx) {
    return new Response('Hello World!');
  },
};

The worker code was deployed direct by the Cloudflare Dashboard UI, but after this, I see a request time of 180 - 380ms, It's normal? How can I fix it?

Some details:
Worker URL: https://worker-spring-wildflower-8be3.nuinalp-ltda.workers.dev
Plan: Paid (New standard price)
CF-Ray Response: 820d6602edec2206-MIA
My region: South America (Sao Paulo)
Average response time: 130ms - 380ms

MIA means you're being taken to a colo in Miami rather than something close to you (like GRU)

Is there any specific reason for this? How can I fix it? Or is it a problem with Cloudflare?

Take a look here to see why the Cloudflare datacenter you are routed towards isn't always the closest geographically: https://www.cloudflare.com/en-gb/learning/cdn/glossary/anycast-network/

UPDATEUPDATE: Creating a CNAME on my main domain and pointing it to my Worker, it is now redirecting to GRU and delivering a response rate of 26.4ms
