### Concurrencia y Hamburguesas

Esta idea de código **asíncrono** descrita anteriormente a veces también se llama **"concurrencia"**. Es diferente del **"paralelismo"**.

**Concurrencia** y **paralelismo** ambos se relacionan con "diferentes cosas sucediendo más o menos al mismo tiempo".

Pero los detalles entre *concurrencia* y *paralelismo* son bastante diferentes.

Al añadir `standard`, Uvicorn instalará y usará algunas dependencias adicionales recomendadas.

Eso incluye `uvloop`, el reemplazo de alto rendimiento para `asyncio`, que proporciona un gran impulso de rendimiento en concurrencia.

Cuando instalas FastAPI con algo como `pip install "fastapi[standard]"` ya obtienes `uvicorn[standard]` también.

Concurrency
===========

This document describes the concurrency considerations for http/2 connections and the connection pool within OkHttp.

## HTTP/2 Connections

The HttpURLConnection API is a blocking API. You make a blocking write to send a request, and a blocking read to receive the response.

#### Blocking APIs

	go func() {
		defer xioutil.SafeClose(ch)

		concurrency := opts.concurrencyStart

		if opts.autotune {
			// if we have less drives than concurrency then choose
			// only the concurrency to be number of drives to start
			// with - since default '32' might be big and may not
			// complete in total time of 10s.
			if globalEndpoints.NEndpoints() < concurrency {
				concurrency = globalEndpoints.NEndpoints()
			}

### Concorrência e hambúrgueres

Essa idéia de código **assíncrono** descrita acima é às vezes chamado de **"concorrência"**. Isso é diferente de **"paralelismo"**.

**Concorrência** e **paralelismo** ambos são relacionados a "diferentes coisas acontecendo mais ou menos ao mesmo tempo".

Mas os detalhes entre *concorrência* e *paralelismo* são bem diferentes.

### Concurrency and Burgers { #concurrency-and-burgers }

This idea of **asynchronous** code described above is also sometimes called **"concurrency"**. It is different from **"parallelism"**.

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.
