I’d asked about using a VPS to get better routing to my homelab in this post: https://lemmy.world/post/1424540

I’ve narrowed down my problem- if i use a subdomain in my caddyfile, performance is 1/3 or worse compared to just the root.

example.com {reverse_proxy 192.168.1.57}

will saturate my gigabit lan connection at 980ish. On a 5gUW connection i get my advertised 50 mbit or more

librespeed.example.com {reverse_proxy 192.168.1.57}

I get 220-250 megabits on my internal lan. The same 5gUW connection will only get 7 or 8 mbit.

It’s strange to me that everything seems to work just fine, but it’s just slow. Anyone got any ideas?

    is it possible the subdomain resolves to an ip your router can’t see due to nat hairpinning?

      I tried to dig into that but couldn’t come up with a good test. But if NAT hairpinning wasn’t working right, I’d be limited to my ISPs 50Mbit, right? I could get 200+ Mbit on wifi. I also tested this from work (50 Mbit sym fiber) and subdomains always were slower. I figured out today it’s HTTP/3 causing my problems. I don’t know if I care to troubleshoot anymore since it’s working great with http 1 & 2.
