JavaScript-WeChat public number test interface, send messages slow, even send a few times to reply once

1. When the client tests the public number interface, the server replies to the message is slow, and sometimes even send a few messages to reply to one;
What is the reason? Network reason or configuration what is the relevant? By the PHP+JS, the server uses Sina's cloud SAE, which is the language.

2. By the way, there is a "Web Developer Tool" tutorial how to use, concise introduction of which. How can this tool be used for debugging? A good developer tool! Can not be used to develop???

Web Developer tools are used for debugging during the development process. is debugging not part of development?

Server-side reply message very slow feeling should be related to the network environment, or with your code? Did you respond slowly, causing the message to become clogged?
Anyway you this situation I have not met, to PHP also not familiar, I use Java development time did not encounter very slow situation

1, first to troubleshoot is not your business logic has a problem. Then go to the Interface debugging tool to test the interface to determine whether the interface problem.
2, Web Developer tools, I feel too concise, the function is very few. Where to take any tutorials.
