When TPS is high, mux handler dropped messages.

Hi, dear go-diameter author: Thanks for your code, and I used it to build a good diameter client program. But I found, when I send requests in a high rate(above 50 entries per seconds), and the anwser came back also in that rate. Some answers were dropped. I just write a few code in answers handler, so it should not comsume much CPU time (only a number++), I guess the buffer in your code is too short for buffering the incoming answers. Is there any possible to adjust that? Wait for your response. Thanks.

Ignore this issue, after debug, no problem for the package.
