一、前言

异步编程在构建高性能 Web 应用中起着关键作用，而 FastAPI、Sanic、Tornado 都声称具有卓越的性能。本文将通过性能压测对这些框架与Go的Gin框架进行全面对比，揭示它们之间的差异。

二、环境准备

系统环境配置

压测工具

工具	介绍	官网/Github
ab	Apache的压力测试工具,使用简单	httpd.apache.org/docs/2.4/pr...
wrk	高性能多线程压力测试工具	github.com/wg/wrk
JMeter	功能强大的压力/负载测试工具	github.com/apache/jmet...

这里选择 wrk 工具进行压测，mac 安装直接通过brew快速安装

bash 复制代码

brew install wrk

window安装可能要依赖它的子系统才方便安装，或者换成其他的压测工具例如JMeter。

web框架

框架	介绍	压测版本	官网/Github
FastAPI	基于Python的高性能web框架	0.103.1	fastapi.tiangolo.com/
Sanic	Python的异步web服务器框架	23.6.0	sanic.dev/zh/
Tornado	Python的非阻塞式web框架	6.3.3	www.tornadoweb.org/en/stable/
Gin	Go语言的web框架	1.9.1	gin-gonic.com/

Fiber	todo	todo	gofiber.io/
Flask	todo	todo	github.com/pallets/fla...
Django	todo	todo	www.djangoproject.com/

数据库配置

数据库名	介绍	压测版本	依赖库
MySQL	关系型数据库	8.0	sqlalchemy+aiomysql
Redis	NoSQL数据库	7.2	aioredis

三、wrk 工具 http压测

FastAPI

普通http请求压测

依赖安装

python 复制代码

pip install fastapi==0.103.1
pip install uvicorn==0.23.2

编写测试路由

python 复制代码

from fastapi import FastAPI


app = FastAPI(summary="fastapi性能测试")


@app.get(path="/http/fastapi/test")
async def fastapi_test():
    return {"code": 0, "message": "fastapi_http_test", "data": {}}

Uvicorn 运行，这里是起四个进程运行部署

python 复制代码

uvicorn fastapi_test:app --log-level critical --port 8000 --workers 4

wrk压测

开20个线程，建立500个连接，持续请求30s

python 复制代码

wrk -t20 -d30s -c500 http://127.0.0.1:8000/http/fastapi/test

压测结果

python 复制代码

➜  ~ wrk -t20 -d30s -c500 http://127.0.0.1:8000/http/fastapi/test

Running 30s test @ http://127.0.0.1:8000/http/fastapi/test
  20 threads and 500 connections
  
  Thread Stats   Avg      Stdev     Max   +/- Stdev
    Latency     3.06ms    2.89ms  36.65ms   85.34%

Transfer/sec:     12.74MB

Thread Stats 这里是 20、30个压测线程的平均结果指标

平均延迟(Avg Latency):每个线程的平均响应延迟
标准差(Stdev Latency):每个线程延迟的标准差
最大延迟(Max Latency):每个线程遇到的最大延迟
延迟分布(+/- Stdev Latency):每个线程延迟分布情况
每秒请求数(Req/Sec):每个线程每秒完成的请求数
请求数分布(+/- Stdev Req/Sec):每个线程请求数的分布情况

Socket errors: connect 267, read 100, write 0, timeout 0，是压测过程中socket的错误统计

connect:连接错误,表示在压测过程中,总共有 267 次连接异常
read:读取错误,表示有 100 次读取数据异常
write:写入错误,表示有0次写入异常
timeout:超时错误,表示有0次超时

MySQL数据查询请求压测

这里在简单试下数据库查询时候的情况

首先先补充下项目依赖

python 复制代码

pip install hui-tools[db-orm, db-redis]==0.2.0

hui-tools是我自己开发的一个工具库，欢迎大家一起来贡献。github.com/HuiDBK/py-t...

from py_tools.connections.db.mysql import SQLAlchemyManager, DBManager

app = FastAPI(summary="fastapi性能测试")


async def init_orm():
    db_client = SQLAlchemyManager(
        host="127.0.0.1",
        port=3306,
        user="root",
        password="123456",
        db_name="house_rental"
    )
    db_client.init_mysql_engine()
    DBManager.init_db_client(db_client)


@app.on_event("startup")
async def startup_event():
    """项目启动时准备环境"""

    await init_orm()
    
@app.get(path="/http/fastapi/mysql/test")
async def fastapi_mysql_query_test():
    sql = "select id, username, role from user_basic where username='hui'"
    ret = await DBManager().run_sql(sql)

    column_names = [desc[0] for desc in ret.cursor.description]
    result_tuple = ret.fetchone()
    user_info = dict(zip(column_names, result_tuple))

    return {"code": 0, "message": "fastapi_http_test", "data": {**user_info}}

wrk压测

python 复制代码

wrk -t20 -d30s -c500 http://127.0.0.1:8000/http/fastapi/mysql/test

python 复制代码

➜  ~ wrk -t20 -d30s -c500 http://127.0.0.1:8000/http/fastapi/mysql/test

Running 30s test @ http://127.0.0.1:8000/http/fastapi/mysql/test
  20 threads and 500 connections

  Non-2xx or 3xx responses: 140
  
Requests/sec:   5989.59

可以发现就加入一个简单的数据库查询，QPS从 76357.51 降到 5989.59 足足降了有10倍多，其实是单机数据库处理不过来太多请求，并发的瓶颈是在数据库，可以尝试加个redis缓存对比MySQL来说并发提升了多少。

Redis缓存查询压测

    )

    return {"code": 0, "message": "fastapi_redis_test", "data": {**user_info}}

运行

python 复制代码

缓存信息

添加了redis缓存，并发能力也提升了不少，因此在业务开发中一些查多改少的数据可以适当的做缓存。

压测结论

压测类型	测试时长	线程数	连接数	请求总数	QPS	平均延迟	最大延迟	总流量	吞吐量/s
普通请求	30s	20	500	2298746	76357.51	3.06ms	36.65ms	383.64MB	12.74MB
MySQL查询	30s	20	500	730083	5989.59	38.81ms	226.42ms	36.95MB	1.23MB
Redis缓存	30s	20	500	730083	24257.09	9.60ms	126.63ms	149.70MB	4.97MB

给 mysql 查询加了个 redis 缓存 qps 提升了 3倍多，对于一些查多改少的数据，根据业务设置适当的缓存可以大大提升系统的吞吐能力。其他框架我就直接上代码测，就不一一赘述了，直接看结果指标。

Sanic

压测方式都是一样的我就不像fastapi一样的一个一个写了，直接写全部压测然后看结果

环境安装

性能

从性能角度来看，各个Web框架的表现如下：

Gin > Sanic > FastAPI > Tornado

Gin：在普通请求方面表现最佳，具有最高的QPS和吞吐量。在MySQL查询中，性能很高，但最大延迟也相对较高。gin承受的并发请求最高有 1w qps ，其他python框架都在5-6k qps，但gin的mysql查询请求最大延迟达到了1.12s， 虽然可以接受这么多并发请求，但单机mysql还是处理不过来。

还有非常重要的一点，cpython的多线程由于GIL原因不能充分利用多核CPU，故而都是通过开了四个进程来处理请求，资源开销远远大于go的gin，go底层的GMP的调度策略很强，天然支持并发。

注意：Python使用asyncio语法时切记不要使用同步IO操作不然会堵塞住主线程的事件loop，从而大大降低性能，如果没有异步库支持可以采用线程来处理同步IO。

综合评价

除了性能之外，还有其他因素需要考虑，例如框架的社区活跃性、生态系统、文档质量以及团队熟悉度等。这些因素也应该在选择Web框架时考虑。

最终的选择应该基于具体需求和项目要求。如果性能是最重要的因素之一，那么Sanic和go的一些框架可能是不错的选择。如果您更关注其他方面的因素，可以考虑框架的社区支持和适用性。我个人还是挺喜欢使用FastAPI。

五、测试源代码

Github上已经有其他语言的web框架的压测，感兴趣也可以去了解下： web-frameworks-benchmark.netlify.app/result

不知道为啥他们测试的python性能好低，可能异步没用对😄
