Too much delay in connections throw the proxy

[Serginho]

I'm using the proxy in a angular project with a local server and there is an important delay when the proxy is up.

Comparative requests: Request --- Proxy --- Server request1 --- 15.3s --- 602ms request2 --- 5.8s --- 387ms

Why does the proxy have that delay?I think it's too much delay.

I fixed it partially, If you choose a port different to 80, the proxy works better and more quick.
