As QUIC promises better performance than HTTP/2 and Google is already using it, it should be interesting to enable QUIC on our server and see it impacts the loading performance.

Chrome supports QUIC. Several other browsers do so.

Is it possible to do so?

At this time it appears Litespeed is the only web server providing support for QUIC. Brief research shows QUIC adoption is very low across the Internet, possibly due to the RFC still being in flux. When the RFC moves beyond the proposed we can expect to see more web servers adopt it.

Interestingly, a report in The Register states that only about 161K domains are using QUIC. That is very low adoption (compared to the hundreds of millions of domains that are registered). Article: Google's 'QUIC' TCP alternative slow to excite anyone outside Google
