responsible for managing how many simultaneous requests you make. Too many simultaneous connections wastes resources; too few harms latency.

For asynchronous calls, [`Dispatcher`](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-dispatcher/) implements policy for maximum simultaneous requests. You can set maximums per-webserver (default is 5), and overall (default is 64)....
