我正在建立一個「流量激增」應用程序，可以在幾分鐘內一次性處理 0 - 50,000 個客戶端。我想我會請求你們幫助理解我是否在這裡做錯了什麼。
目前，我正在使用 loader.io 進行測試，此負載測試的配置是 1 分鐘內 0 到 10,000 個用戶端。測試人員唯一要做的就是載入登入頁面，僅此而已，甚至沒有登入。

我的php-fpm配置如下：
pm.max_children 3000
pm.max_requests 200
pm dynamic
pm.start_servers 1500
pm.min_spare_servers 300
pm.max_spare_servers 1500

50GB RAM (I have provided this to the container), server has 64 total.
奇怪的是，即使採用這種配置，我仍然收到「似乎很忙」的訊息！
這是事情死亡的地方：
這裡要記住的最重要的事情是，通常我們的流量很少甚至沒有，但我們預計幾分鐘內就會有多達 50,000 個用戶。你們能幫我解決這個錯誤嗎？謝謝！
答案1
您需要記住，啟動這些額外的工作進程需要時間，正如您在日誌中看到的，php-fpm 一次產生 32 個子進程。最簡單的「修復」是將最小和最大伺服器設定為相同的值，這樣，您就不需要等待它們啟動。
另外，如果可能的話，不要嘗試做類似的事情，而是嘗試實現緩存，因為它總是會更快。
