# Benchmarks { #benchmarks }

Independent TechEmpower benchmarks show **FastAPI** applications running under Uvicorn as [one of the fastest Python frameworks available](https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7), only below Starlette and Uvicorn themselves (used internally by FastAPI).

But when checking benchmarks and comparisons you should keep the following in mind.

//     if v is nil, len(v) is zero.
//
// For some arguments, such as a string literal or a simple array expression, the
// result can be a constant. See the Go language specification's "Length and
// capacity" section for details.
func len(v Type) int

// The cap built-in function returns the capacity of v, according to its type:
//
//   - Array: the number of elements in v (same as len(v)).

Secret Computation of the Ephemeral Unified Model // scheme specified in NIST SP 800-56A Rev. 3, Section 6.1.2.2. // Per Section 5.6.2.3.4, Step 1, reject the identity element (0x00). if len(k.pub.q) == 1 { return nil, errors.New("crypto/ecdh: public key is the identity element") } // SetBytes checks that (x, y) are reduced modulo p, and that they are on // the curve, performing Steps 2-3 of Section 5.6.2.3.4. p, err := c.newPoint().SetBytes(peer.q) if err != nil { return nil, err } // Compute P...

由于这是一个 WebSocket，抛出 `HTTPException` 并不是很合理，而是抛出 `WebSocketException`。

您可以使用[规范中定义的有效代码](https://tools.ietf.org/html/rfc6455#section-7.4.1)。

# Tutorial - Guía del Usuario { #tutorial-user-guide }

Este tutorial te muestra cómo usar **FastAPI** con la mayoría de sus funcionalidades, paso a paso.

Cada sección se basa gradualmente en las anteriores, pero está estructurada para separar temas, de manera que puedas ir directamente a cualquier sección específica para resolver tus necesidades específicas de API.

* editor (meaning component of IDE): редактор кода
* adopt (meaning start to use): использовать (or `начать использовать`)
* headers (meaning HTTP-headers): HTTP-заголовки
* cookie sessions: сессии с использованием cookie
* tested (adjective): протестированный
* middleware: middleware (don't translate, but add `промежуточный слой` if clarification is needed)
