Even with top tier private tracker, you'll never achieve 1 gbps speed and have to wait the same amount as anyone on 300 mbps connection. Thts y i said, 1 gbps connection doesnt exist outside your ISP network and I'd categorize anything more than 500 mbps plan a SCAM !!
My calculation based on my previous Gigabit internet usage is that, you're averaging out at 300 mbps on the internet. You may achieve higher speed when you download say For ex: linux ISO/Software/Games hosted in CDN but other than that, no chance.
I'm not challenging anyone here, just wanted to see if we can achieve the high speed as advertised or such use cases so please share some screenshots/video if you can.
