Slow Mac WiFi but Internet Fine on PC?

Occasionally, my internet gets REALLY slow on my laptop. Then I go use my wife's PC and everything is fine. Since few things are more aggravating than Windows machines working better than Macs, I decided to post this solution so I won't forget it.

Problem

MacBook Pro internet is slow over wifi and ethernet.

Symptoms

• After opening several tabs, they all show no content--just perpetual spinning
• Things worked fine for a few seconds, then suddenly, everything is slow
• You see none of these issues on your Windows machine on the same network
• You do not have this issue on your mobile phone or tablet, using WiFi

Solution

Add DNS servers in "System Preferences > Network" under the "Advanced" options. By default, my settings were pointing to Comcast. Once I added Open DNS, instead, everything worked fine.
