I tried:
-Googling - No answer
-Playing with sysctl - Broke completely
-Dic*ing around in BIOS - Did nothing
-Ndiswrapper - Kernel panicked
-Crying - Also nothing changed

On Linux pings are like 1ms or so
Code:

[root@maciek ~]# ping 1.1.1.1 PING 1.1.1.1 (1.1.1.1): 56 data bytes 64 bytes from 1.1.1.1: icmp_seq=0 ttl=56 time=12.743 ms
This is a normal response time. I get around 8ms on my FreeBSD laptop via wireless and exactly the same 8ms on my Linux gaming PC.
Cloudflare's DNS is still faster then Google's 8.8.8.8 which gives me around 15ms at the moment of testing.
Those response times will vary by the time of day and where you are in the world, i guess.

On Linux pings are like 1ms or so
Nope, that sounds more like you pinged on the local network? Proof?

1ms does sound extremely low. Maybe if you lived a few doors down from MAE-EAST or MAE-WEST
Code:
PING 1.1.1.1 (1.1.1.1): 56 data bytes
64 bytes from 1.1.1.1: icmp_seq=0 ttl=251 time=8.971 ms

64 bytes from 1.1.1.1: icmp_seq=2 ttl=251 time=8.804 ms
64 bytes from 1.1.1.1: icmp_seq=3 ttl=251 time=9.211 ms
64 bytes from 1.1.1.1: icmp_seq=4 ttl=251 time=9.504 ms
