| Summary | 0011223: enable HTTP 2+3 on server(s) | ||||
| Description | Some clients try HTTP3 by default, which would explain higher latency for first download. We should enable HTTP3 on all of our servers at this point. | ||||
| Tags | No tags attached. | ||||

I've done uptimekuma.taler.net for testing, seems to work fine. |
|
|
I enabled it for demo. wget (http/1) takes 120ms, wget2 (http/3) takes 76ms on my current connection. |
|
|
todo: enable on rusty/spec. |
|
|
Lessons learned: nginx.conf:: http { + http2 on; + http3 on; + quic_retry on; + ssl_early_data on; } then have ONE section + listen 443 quic reuseport; + listen [::]:443 quic reuseport; but everywhere else (reuseport MUST only be specified once!) + listen 443 quic; + listen [::]:443 quic; |

Doesn't seem to make much of a difference in Android at least to disable all protocols other than HTTP/1.1, just FTR. Not sure about iOS. |
|
|
Eh, (1) are you sure you actually used HTTP/3? Over a wireless connection / limited bandwidth? (2) Note that it's only available on demo. (3) Make sure you didn't have /keys already cached, too... I did notice it making quite a difference for wget/wget2, so I'd be surprised if it made no difference, assuming it was properly enabled/disabled... |
|
|
I made sure the app did NOT use HTTP/2 or HTTP/3, in order to rule out the "Some clients try HTTP3 by default" causing fetches to be slower. And I don't think I have HTTP caching enabled anyway. |
|
|
Ok, but did you also try WITH http/3 enabled on the client-side to compare? |
