Swoole Love PHP

今天公司內訓的簡報摘錄。

研究 Swoole 多年，也確實在上線環境正式運行很久且穩定，所以與同事分享點滴與技巧。

除了一點範例程式外，分享著重的是【架構】差異，延伸出去再與 Nginx/PHP, Node 及 Go 進行一些比較。

主要是提出幾個問題，希望引發思考：

➊ 很多人都說 Swoole 快，是哪裡快？(其實我覺得網路上的資訊不夠全面，講得也不一定為真)

➋ 猜想 Nginx/PHP, Swoole, Node, Go 基礎效能比較？還能最佳化嗎？何處著手？

➌ 其他。

    Why not Go(lang)

38. 38/39
    Why not Go(lang)
    ➊ Not most developers in company are familiar with Go(lang).
    ➋ Not so many Go(lang) developers in Taiwan (future?).
    ➌ Training time.
    ➍ Swoole performance is close to Go(lang) in some cases.
