Linux internet dropping occasionally using HTTP Proxy

In order to use internet at my university campus I need to set an HTTP Proxy which under Windows 10 works *ok without latency and connection problems unless (*I say ok because at peak hour everything is painfully slow).
The problem is on linux where the speed is negatively impacted in relation to windows 10 and has terrible latency, waiting 4-6 seconds just for initial DNS lookup.
Sometimes the page doesn't load at all and I have to refresh 2-3 times.
If I open 3-4 tabs under chrome and the dns resolves the 5 tab isn't loading at all (Waiting for socket...).

INFO:
- http_proxy: department.university.com
- proxy_port: 8080

I'm on ArchLinux with Gnome (previously xfce4 but a bit hard to set/unset proxy).

Is there any way I can solve those problems under arch? I disabled ipv6 because of some errors in dmesg.

Re: Linux internet dropping occasionally using HTTP Proxy

Are your gnome 3 settings correct ?

I disabled ipv6 because of some errors in dmesg.

Does latency improve if you re-enable ipv6 ?
