php - What can bottle neck cURL's mult functions in PHP?

Question

Using cURL_multi is great for simultaneous connections, but what can limit the number of connections? I ask because when doing over 500 some of them seem to randomly fail to connect. I am doing HEAD requests with a timeout of 5, and increasing the timeout to 10 didn't seem to help. Any ideas?

Answer 1

500 の同時接続? サーバーがあなたへのサービス提供を拒否している可能性があります。

4 ～ 12 の同時接続数の間で、より合理的な制限を設定してみてください。
