How to resolve slow performance of PHP using a curl proxy?

If the CURL proxy is running extremely slowly, there are several possible solutions:

  1. Utilize optimized proxy servers: prioritize selecting fast and stable proxy servers. You can select the best proxy server by querying and comparing the speed and stability of different proxy servers.
  2. Optimize CURL connection timeout: Adjusting the CURL connection timeout can help reduce waiting time. You can set the connection timeout by adjusting the CURLOPT_TIMEOUT and CURLOPT_CONNECTTIMEOUT options.
  3. Increase the number of concurrent CURL connections: You can increase the number of concurrent CURL connections by setting the CURLOPT_MAXCONNECTS option. This allows for multiple connections to be made simultaneously, improving overall request speed.
  4. Enabling HTTP Keep-Alive allows multiple HTTP requests to be sent over a single TCP connection, reducing the time taken for establishing and closing connections. This can be achieved by enabling the CURLOPT_TCP_KEEPALIVE option.
  5. Using connection pool: Reusing established connections helps to avoid frequent opening and closing of connections. The CURLOPT_FORBID_REUSE option can be set to disable the connection pool.
  6. Using multithreading allows you to send multiple requests simultaneously, improving the overall speed of requests. You can use PHP’s multithreading extension or a multiprocessing library to implement multithreading.
  7. Adjusting server configuration: If the proxy server is self-built, you can adjust the server configuration to improve the performance of the proxy server. This can involve increasing the server’s bandwidth, optimizing the server’s network settings, and so on.

The above are some common solutions, specific solutions may vary depending on the situation. It is recommended to try different methods to address the problem according to the specific circumstances.
