My ISP seems to be throttling my VPN connection. Just started a week or so ago. Anyone have any tips for correcting this shit?

Edit: Sorry, I didn't leave much info. I guess I was thinking in more general terms. I use PIA, have for years. I've tried to change protocols and ports, my VPN speed still sits around 10K. Just ridiculous. Speed test without VPN:

SOLVED!! OK, I'm an absolute idiot. The tl;dr I had accidentally toggled the Toggle Alt. Rate Limits setting. Thank you everyone for attempting to help that which couldn't be helped!
