Eggman was using something called the Super Genesis Wave to fuse their Universe with the Megaman Universe.
Super Sonic tried to use Chaos Control to stop the process but Eggman interrupted him before he could finish finetuning it. He unleashed the Chaos Control and while it stopped the merger, it also destroyed every Sonic alternate Universe save for his own and Blaze's
Tell Flash to run 146k light years on the cosmic interstate in an instant just to get from one universe to the next. Not mentiong how many light years across the universe itself which varies lol. Sonic and knuckles were running so fast and collided on accident, and destroyed an entire universe lol they both survived unscathed. You know how durable you gotta be to survive a universal destruction event that you're The epicenter of? Lol come on now.

I'm probably familiar with most feats you could post, yeah.
But what I will say is that many of the high-end Sonic feats you'll find posted around the interwebs tend to ignore underlying context, and aren't quite as uber as some may think... Most people just haven't read the material themselves, so they aren't familiar with said context.
That being said, base Sonic could casually operate by the picosecond:
He was also at least 2x light speed:
And if Super Sonic is allowed(which you seemed to indicate in the OP), then he's 1,000x faster and all around more powerful than base Sonic:
And it was indicated that he could control the chaos energy to such an extent that he could rewrite the universe:
