Mikrtik 6.35.1 CHR Proxy

I’ve redirected tcp 80/8080/3128 ports to 8080 web proxy …

and tried to test performance via speedtest

without 95/95 (max of current connection) with web-proxy -75/80

why its so weak ?

Second question proxy override gateway ip to internal ip that is not good how to fix it ?

And one more question how to shape speed if I marked connection before for different direction in I have two rules (simple quee) for each ip … traffic after going thrue proxy lose all markers …
