Repeatedly we're seeing questions on when http/3 will be implemented. http/3 is available in the experimental branch of Nginx, called "main line". This is not a branch that is "stable". Plesk only offers stable software versions for the utmost reliability you can get as reliability is much more important than speed. A fast website is of no use if its webserver crashes or the protocol doesn't work as expected in all cases. Plesk does not offer experimental features. The stable version of Nginx that supports http/3 is expected to become available in April 2024. This is when it makes sense for Plesk to also offer http/3.

From articles that foster the hype about http/3, it sounds as if it can increase a website's speed incredibly much. On average, on real website tests by several reknown sources, the acceleration has been seen at around 0.2 to 0.3 s/page, typically around 12 % improvement compared to http/2, but it depends on the actual website content. Most website owners will be able to increase the speed of their sites dramatically more by reviewing the scripts/plugins/themes they use, because most issues of slow websites are caused by bad software.

If you comment here that http/3 is a "critical feature" (as we've seen many such comments), please also argue, why this is such a critical feature.

    Wait a minute, since when Plesk = Nginx?
    If that's the case, it would be nice to let people know.

    I mean, I don't use Nginx and I'm not the only one I'm sure.

    One could even make the case for OpenLitespeed, but for what?
    You don't hear your clients and just go ahead and build useless stuff like that sitejet thing.

    It's easy to understand.
    How could you make money on stuff like HTTP/3 or Varnish?
    The same things which are on the top requests.

    And for what's worth, HTTP/3 and Nginx are already equivalent on users:

    https://www.wappalyzer.com/technologies/miscellaneous/http-3/

    Wondering how popular it has to be to make it on Plesk.
    But hey, it's almost that time of the year. January. Where you bump the price every single time for no reason at all.

    As described in the article, 12% more speed of http3 compared to http2 is a lot for just activating something in a web server / web proxy like a *.so / module!
    So I've been wanting this feature for a long time ~2021, because from then on this feature will soon be standard at Cloudflare.
    Http3 will replace Http2, since it is simply the first big player to support it.

    I've known Plesk since version 8.x, although I technically know how things work under Linux. I love Plesk because the interface simplifies many things and the customizing has also improved a lot.

    What do you think of Plesk's idea of offering Nginx in the installer with http3 (experimental) and once with http2 (stable)?

    I hope to be implemented as a free feature but not as paid feature...

    > It's a critical feature. Please implement urgently on NGINX !

    "nginx-1.25.0 mainline version has been released, featuring experimental HTTP/3 support." (c) nginx news/changelog

    Usually, Plesk uses stable versions of products. Currently, HTTP/3 in the nginx is in "mainline" branch only (not "stable"). It means, when the nginx "stable" version be released, it makes sense to bring support in Plesk.

    It is very important please implement it.

    It would have great impact to have this feature. But this will take years to get and most probably HTTP/4 would come sooner. What i fear is that this is going to be paid feature.

  • Michele Mincone commented  ·   ·  Report

    Yes. this feature is important for the future of the Web, QUIC protocol is great. NGINX 1.25.0 supports http/3. Another thing that could be really helpful is adding a module to install OPENLITESPEED instead of having only the option for litespeed enterprise.

    With openlitespeed/litespeed, beyond the PLESK interface that will be there, you have the openlitespeed admin panel and litespeed admin panel so you can directly configure the web server, for example, adding brotli compression on the fly or enabling QUIC - HTTP/3.

    This admin panel for this web server is really great. It saves up a lot of time.

    Thanks if you take into account these improvements. They'll be great!

    Very important - this is the future of the web, with shorter repose time!
