Fix OpenFeign Slow Requests: Guide

If OpenFeign is slow to receive requests, you can try the following solutions:

1. Adjusting connection timeout and read timeout: In the configuration of OpenFeign, you can set the connection timeout and read timeout, and making appropriate adjustments to these times can reduce waiting time.
2. By utilizing connection pooling, OpenFeign defaults to using Apache HttpClient as its HTTP client, allowing for the configuration of HttpClient connection pools to manage HTTP connections and improve request processing efficiency.
3. Adjusting the thread pool size: OpenFeign by default uses Hystrix to implement circuit breaking and thread pool isolation. The size of the thread pool can be adjusted according to actual circumstances to prevent thread starvation and blocking.
4. Using asynchronous requests: OpenFeign supports asynchronous requests, allowing the sending and receiving processes to be asynchronous through the @Async annotation, which improves concurrent processing capability.
5. Cache the request results: If the results of a request are constant and frequently used, it may be beneficial to cache the results to avoid frequent requests to the backend service.

The above methods can improve the processing speed of OpenFeign in handling requests, reducing the wait time.
