Configuration options for mod_pagespeed/ngx_pagespeed

[Gabriel Torres]

Hi,

Following Dmacleo's advice, I installed ngx_pagespeed. Now I am stuck with how to configure it... There are too many options!

http://ngxpagespeed.com/ngx_pagespeed_example/

Any suggestions of the options that will improve IPB load time and won't generate any kind of issue?

Thanks,

Gabriel.

After playing with this for a couple of hours, here is my current configuration:

pagespeed EnableFilters defer_javascript,collapse_whitespace,combine_css,combine_javascript,elide_attributes,extend_cache,remove_comments,insert_dns_prefetch,lazyload_images,inline_javascript,local_storage_cache,outline_css,outline_javascript,prioritize_critical_css,rewrite_css,rewrite_javascript,rewrite_style_attributes,trim_urls;

The option that gives the best result is defer_javascript. Especially on our forums, where we have several advertising banners running, this made the page load first, and then the banners. Fantastic results. However, this option generates a conflict with the >Lazyloader hook, and the images are shown as broken The solution was very easy: I disabled this hook and enabled the integrated lazy loader (lazyload_images).

Additional comments and suggestions are more than welcome.

Here you go, my recommendations and advice;

I added apache version there based on your filters.

Had to disable defer_javascript today... A few users complaining that JavaScript-based features were not working for them (but working just fine for me).

Sorry, I haven't see that Kirito is already managing a topic that has exactly what I was looking for... Therefore I am moving the discussion there: http://community.invisionpower.com/topic/397051-pagespeed-web-server-module/

Admin/moderators can even delete this topic if they want. Thanks.

Are you still using this feature? Does it break IPS? Does it solve CSS render blocking?

[Makoto]

I don't use that setting anymore. Causes too many reflow issues and is highly inconsistent.

ymmv though.

Do you have an updated full config you'd be willing to post?

@sobrenome I have this module for nginx disabled, I don't remember exactly why I had disabled it, it's been six years. I have only the PHP built-in opcode cache enabled at the moment.

I really would like to test prioritize_critical_css, but I am afraid that on long term it could hurt TTFB considering lots of on the fly optimizations.

Yeah it doesn't really work well with IPS at the moment, and the mod_pagespeed project hasn't seen development in quite a while now.

I can post the configuration I currently use later though I don't think its changed too much. I've mainly just disabled image filters as I use Cloudflare now and it takes care of that for me.
