Earlier today I was looking for a site that had both Brotli and GZip enabled for testing and comparing. I couldn't find any, so I rebuilt NGinx with the ngx_brolti module and enabled it here on Celly.Space.
So far browser support is limited, But the results look promising. I picked up about a 5% increase in compression overall, the best results coming from text files. So, if your site is js/css heavy, this may be worth looking into.
Note: I'm using default config for both GZip and also Brolti.
So, enjoy! Or Not? Who knows, perhaps someone out there enjoys my web server compression fetish.
