HTTP/3 (Quic) is advertised as it reduces round trip time by using UDP instead of TCP. In theory, it reduces response time on slow connections (high latency). When I take a test on my computer, I see nearly no difference. Am I making a mistake or which tool to use to see a difference?
I have two servers in the same country which have roughly 50ms latency on a regular cable connection. I use Chrome / Dev Tools -> Network Throttling.
In theory, http3 should be faster on a 3G and Slow 4G connections but it is not.
Cable Connection: HTTP2: ~50ms HTTP3: ~50ms
Fast 3G: HTTP2: ~585ms HTTP3: ~565ms
4G Slow: HTTP2: ~155ms HTTP3: ~155ms
4G Regular: HTTP2: ~55ms HTTP3: ~55ms
