壓測connections 最大只有2048

yifenbushe 2022-03-22

使用workerman壓測腳本測試gateway，只有2048個(gè)connections，這就是極限了嗎？已經(jīng)按照要求安裝擴(kuò)展和優(yōu)化內(nèi)核，環(huán)境是centos8/php8

你貼的壓測腳本里限制了，最多發(fā)出2000連接。

多謝walkor老師，這么晚了還沒休息回答問題，贊一個(gè)?。?！
現(xiàn)在數(shù)量上來，但是connections一直在1.5萬和3千左右跳動(dòng)變化，這個(gè)正常嗎

還有優(yōu)化空間嗎
walkor 2022-03-23

配置好的話gatewayWorker單機(jī)支持10萬連接很輕松。
但是壓測腳本最多能發(fā)出2萬左右的連接，因?yàn)閴簻y腳本發(fā)起連接會(huì)消耗本地端口，默認(rèn)本機(jī)端口就大概2萬可用。

業(yè)務(wù)邏輯

class Events
{
    public static function onConnect($client_id)
    {
        Gateway::sendToClient($client_id, "Hello $client_id\r\n");
    }
}

壓測腳本

<?php
require __DIR__ . '/vendor/autoload.php';

$worker = new Worker();

我這1核2G輕服務(wù)器127.0.0.1壓測輕松2萬連接，維持這2萬連接cpu占用2%左右，穩(wěn)定無波動(dòng)。

yifenbushe 2022-03-23

有做其他優(yōu)化嗎？Event.php按照您這么寫完，還是原來那個(gè)樣，connections再1萬上下浮動(dòng)特別大，感覺不穩(wěn)定

壓測有問題繼續(xù)在這里回復(fù)追加提問，不要新開帖子。
