摘要：開(kāi)始測(cè)試是一個(gè)基于的常駐內(nèi)存協(xié)程三模高性能框架，由于該框架同時(shí)具備常駐內(nèi)存模式協(xié)程模式，所以能很方便的測(cè)試結(jié)果。常駐內(nèi)存模式的進(jìn)程數(shù)配置過(guò)多，并發(fā)性能反而會(huì)降低，該問(wèn)題同樣適用于傳統(tǒng)模式。

在現(xiàn)代化 PHP 高級(jí)開(kāi)發(fā)中，Swoole 為 PHP 帶來(lái)了更多可能，如：常駐內(nèi)存、協(xié)程，關(guān)于傳統(tǒng)的 Apache/FPM 模式與常駐內(nèi)存模式(同步)的巨大差異，之前我做過(guò)測(cè)試，大家能直觀的感受到性能的巨大提升，但是協(xié)程到來(lái)后，又帶來(lái)了多少性能的提升呢？提升的又是哪方面的性能？下面逐步測(cè)試一下。

傳統(tǒng)的 Apache/FPM 模式與常駐內(nèi)存模式(同步)的測(cè)試文章：
MixPHP 并發(fā)性能全面對(duì)比測(cè)試

協(xié)程的優(yōu)勢(shì)

協(xié)程模式與常駐內(nèi)存模式(同步)/傳統(tǒng)模式相比：

常駐模式/傳統(tǒng)模式都屬于同步阻塞編程，由于同一個(gè)進(jìn)程不能并行處理請(qǐng)求，所以為了提高并發(fā)，只能開(kāi)啟更多的進(jìn)程，通常超過(guò) 100 甚至更多，每個(gè)進(jìn)程都有基礎(chǔ)的內(nèi)存消耗，加起來(lái)就很多了，而且受限于 Linux 總進(jìn)程數(shù)限制，并發(fā)總數(shù)無(wú)法突破，加上進(jìn)程非常多之后，CPU 需要更多的線程切換，浪費(fèi)了很多性能，當(dāng)然相比 FPM 的傳統(tǒng)模式每次都需從頭開(kāi)始，常駐模式還是要好非常多的，但是協(xié)程顯然更加優(yōu)秀。

協(xié)程模式的執(zhí)行方式：

協(xié)程模式中一個(gè)進(jìn)程可以同時(shí)執(zhí)行 N 個(gè)請(qǐng)求，但同一時(shí)刻只執(zhí)行其中的某一個(gè)請(qǐng)求，也就是說(shuō)，當(dāng)執(zhí)行到 MySQL/Redis 這些客戶(hù)端時(shí)，由于需要等待客戶(hù)端響應(yīng)，常駐模式/傳統(tǒng)模式通常是在傻傻的等待響應(yīng)，而協(xié)程這個(gè)時(shí)候會(huì)掛起當(dāng)前協(xié)程，切換到其他協(xié)程中去處理其他請(qǐng)求，所以協(xié)程能同時(shí)處理 N 個(gè)請(qǐng)求，每增加一個(gè)請(qǐng)求只需增加一些內(nèi)存消耗，相比增加一個(gè)進(jìn)程的內(nèi)存消耗，顯然是少太多的，由于協(xié)程能并行處理，所以通常只需配置于 CPU 數(shù)量 1～2 倍左右的進(jìn)程數(shù)即可，更少的進(jìn)程帶來(lái)更少的 CPU 線程切換，又減少很多性能損耗。

開(kāi)始測(cè)試

MixPHP 是一個(gè)基于 Swoole 的FPM、常駐內(nèi)存、協(xié)程三模 PHP 高性能框架，由于該框架同時(shí)具備常駐內(nèi)存模式、協(xié)程模式，所以能很方便的測(cè)試結(jié)果。

測(cè)試環(huán)境：

docker 容器，限制只能使用 1 CPU。

其他參數(shù)如下：

Server      Name:      mix-httpd
Framework   Version:   1.1.0-RC
PHP         Version:   7.2.9
Swoole      Version:   4.1.0
Listen      Addr:      127.0.0.1
Listen      Port:      9501

代碼：

模擬常用的 HTTP 開(kāi)發(fā)需求，執(zhí)行三個(gè) SQL 請(qǐng)求。

// 默認(rèn)動(dòng)作
public function actionIndex()
{
    PDO::createCommand("select * from `test` where id = 1")->queryOne();
    PDO::createCommand("select * from `test` where id = 2")->queryOne();
    return PDO::createCommand("select * from `test` limit 5")->queryAll();
}

測(cè)試結(jié)果

常駐內(nèi)存模式(同步)：

進(jìn)程數(shù)	并發(fā)數(shù)	RPS
8	100	838.65
8	300	683.78
8	500	688.56
50	100	770.69
50	300	304.90
50	300	378.95

協(xié)程模式：

進(jìn)程數(shù)	并發(fā)數(shù)	RPS
8	100	834.12
8	300	837.50
8	500	824.14

協(xié)程在本次測(cè)試中并沒(méi)有像之前的傳統(tǒng) Apache/FPM 模式與常駐內(nèi)存模式(同步)的測(cè)試一樣展現(xiàn)出巨大的性能提升，說(shuō)明：

在少量能快速響應(yīng)的 SQL 請(qǐng)求中，協(xié)程的提升并不明顯，應(yīng)該要在響應(yīng)時(shí)間更大時(shí)，才能感受到協(xié)程優(yōu)勢(shì)。

常駐內(nèi)存模式的進(jìn)程數(shù)配置過(guò)多，并發(fā)性能反而會(huì)降低，該問(wèn)題同樣適用于傳統(tǒng) Apache/FPM 模式。

常駐內(nèi)存模式(同步)詳細(xì)測(cè)試

首先 8 個(gè) Worker 進(jìn)程，并發(fā) 100 測(cè)試，RPS 為 838.65。
