The server will maintain a thread pool listening for incoming requests. Upon receiving a request, the thread will process the request and return the response. If all the requests are received at the same time and they're fewer than the maximum number of threads in the pool, they will all be services in parallel (though the actual processing will be interleaved based on the number of cores/cpus). If there are more requests than threads, the request will be queued (waiting for a connection) until either a thread frees up or the client request times out.

If you're connecting to the service from a mobile network, there is higher latency in the initial connection but not enough to make a difference.
