Reverse proxy and direct access Ping Performance Analysis

I suddenly felt that the efficiency of direct access and reverse proxy will be somewhat discounted, but what is the discount? Let me test it. See the following figure and table.

Iii. Summary

The performance difference is about 12 ms. For foreign servers, the battle is 1/15 in 12 ms, while for domestic servers, the proportion is 1/2 or 1/3, or even doubled in milliseconds. If a reverse proxy is used for a domestic server, at least Ping must be between 30 and 50. However, for a website, this time is quite enough. Because the general webpage opening time is about 200 ms for Baidu homepage.
