Reverse proxy slows down ajax

I have a situation where special.company.com is reverse proxied to a server with address 123.123.123.123.

At the server locally, the ajax loads in 600ms. However, when running the same 开发者_运维知识库application throught special.company.com, it takes approximately 1.7s.

Is reverse proxy the main cause of the slow down? How can we find a solution to this?

Set up a TCP port forward so you can test the ajax load bypassing the reverse proxy server. This will determine if it's a problem with your remote internet connectivity, or computer.

Your problem requires a process of elimination, to find the cause for sure.
