Sanic ， Fastapi都是優(yōu)秀的python web異步框架檐蚜，找了半天沒找到靠譜的性能對比測試加缘，只能自己做一個(gè)。
測試內(nèi)容：純get請求霹娄、異步ORM讀
測試工具：WRK
測試代碼：由于兩者代碼非常相似能犯，本文就直接放上fastapi的代碼demo了。

3 結(jié)論
3.1 純性能sanic大約是fastapi的2.5倍，sanic單機(jī)并發(fā)接近 4萬?Requests/sec香追，而fastapi只有1.6萬合瓢。
3.2 使用異步ORM進(jìn)行數(shù)據(jù)庫讀時(shí)，瓶頸更多在數(shù)據(jù)庫方面透典，但同樣條件下晴楔，fastapi性能仍然比sanic略低，大約為sanic并發(fā)性能的0.7倍峭咒。
4 感言
python3.6版本以后web的性能真的是可比Golang了（實(shí)測sanic比go的gin框架性能約低一半税弃，但仍處于一個(gè)數(shù)量級），限制服務(wù)器性能的更多時(shí)數(shù)據(jù)庫和帶寬凑队，正常一個(gè)帶數(shù)據(jù)庫讀寫的api接口并發(fā)能到3000已經(jīng)很牛了则果，無論哪個(gè)框架性能都過剩了幔翰。
