Enabling BBR. It worths for websites?

Broscience

Just noticed it inscreased my speed for my VPN and Shadowsocks. Tested on Speedtest. But how about websites, Wordpress and so on? Anyone tested it? Anyone enabled it for your sites?

Building a Better Response ?

I used it and it does not help too much with my websites. Though it does increase visitors' download speed, it cannot reduce TTFB, which is the actual bottleneck for my websites.

To be honest, in my opinion it isn't worth fussing over TCP congestion control algorithm for most websites.

Yes, that's the point. The benefit of BBR is that any connection almost instantly starts transferring at the full possible speed, whereas other algorithms need some time to ramp up. Aside from TTFB that still should help for any at least somewhat large files (like photos), or if you offer some kind of downloads.

I will leave this question to the kernel and os team. I don’t have enough knowledge to understand the math behind and I don't have lots of machines to experiment.

My response is missing in your poll:

• Yes and it's no better or worse than default protocol

It has increased VPN/Streaming performance, never Wordpress / generic websites in my case.

Looks like there is some benefit.

That's a silly response and of course doesn't belong in a poll. "...it's no better or worse..." and then gives an example of it being better. TCP algorithms are very much better or worse than others.

My response is legit and addresses OP question, which you seem to have not read fully (admittedly, OP question changes slightly from title to the poll). OP has asked specifically on websites and Wordpresss engine. My reply was on that. I have not seen improvements with websites, but I added that I have seen improvements with streaming and VPN like OP did.

Interesting read, thanks!

I think it can bring some benefits, but most likely won't be perceptible for most workloads. Useful for CDN edge nodes and that kind of stuff, can't hurt for webservers but not really needed.

@eva2000 an opinion on that?

Proper HTTP/2 prioritization at web server level is important if page speed/seo as per Google's Core Web Vital metrics are important to you for optimizing your critical render path. If you use Cloudflare paid plans, then definitely enable Enhanced HTTP/2 Prioritization And naturally using BBR helps too.
