Request for information: ISPs and P2P throttling

[Kunou]

My lag spikes change based on which world I'm logged in to. Some worlds I have no lag. Unfortunately, on my main world I have terrible lag now. These spikes occur every 5 to 10 seconds, and consist of 1 to 2-second freezes, followed by models quickly animating to their current state.

- Name of ISP - Comcast
- Country of Residence - Sacramento, California, USA
- When does the problem occur (always, only during specific times?) -Always, but way worse in instances. Spikes, lag, and rubberbanding happens at all times. Sometimes party members walk in place for more than 5-7 seconds before everything catches up and moves again.
- Reference number from your ISP, if you raised this matter with them - No reference number, but I have called AND talked on live chat and they insisted that they do not throttle at all.

Also to add, I've port forwarded everything I could (and yes, even opening ports that are not recommended because it's dangerous. Also tried DMZ). I've pretty much tried and have done everything you could find online about this issue. Only thing that works HALF the time is using pingzapper, but you have to pay for that.
