Yeah, I'm not seeing fast uncached times either. I usually hit Cloudflare's Miami datacenter, which is only about 200 miles and very low latency. But I'm seeing 200+ms on this site right now.
Durable objects, r2 as well as tunnel have been particularly poor performing in my experience. Workers has not been a great experience either.
R2 in particular has been the slowest / highest latency s3 alternative I ever had experience with, falling behind backblaze b2, wasabi and even hetzner’s object storage.
