Nginx Brotli - Yes or No?

I have been reading through the performance guide, got to Brotli and am unsure whether to enable it or not in latest beta build.

---

I use cloudflare, so all HTTPS. Am I going to see a benefit enabling Brotli for NGINX behind cloudflare, or am I wasting my time and server resources with Brotli, and better to leave cloudflare do their thing with cached data as sent to them via default centmin install?

 

Ok, so nginx is currently built using --with-zlib=../zlib-cloudflare-1.3.0. When I use the centmin menu 4, is there an option to adjust this and add:

--add-module=ngx_brotli_module

And that will enable it? Do I have to add something to custom config to enable / disable either one?

 

Ok, I thought the cloudflare one was different. But it all works on the same thing, so enable Brotli compression and cloudflare will do its thing with that.

You've thought of everything here it seems.

 

Ok, doing some testing, but ran into a problem.

I removed:

NGXDYNAMIC_BROTLI='y'
NGINX_LIBBROTLI='y'

Rebuilt nginx, and now when doing a webpage test, there is no image compression.

I ran:

Code:

curl -sI /dev/null -H"Accept-Encoding: gzip" https://wotbforum.com/attachments/a-man-laying-on-the-railroad-tracks-not-exactly-the-smartest-thing-to-do_stf-bbp0rj-jpg.2

Code:

I'm not getting Content-Encoding: gzip in my output, and thus at all.

 

Why am I not getting image compression suddenly?

 

Hang on... it doesn't seem that you compress images in the gzip_types
