mod_pagespeed is an open-source Apache module that automatically optimizes web pages and resources on them. Optimization is done by rewriting the resources using filters that implement web performance best practices. Webmasters and web developers can use mod_pagespeed to improve the performance of their web pages when serving content with the Apache HTTP Server. Three steps to mod_pagespeed
mod_pagespeed is available as a downloadable binary for i386 and x86-64bit systems and as open-source code accessible through svn. It is tested with two flavors of Linux: CentOS and Ubuntu. The developer may try to use them with other Debian-based and RPM-based Linux distributions.
Serve your web pages with Apache and mod_pagespeed
Follow the instructions to configure mod_pagespeed with Apache and get familiar with the configuration. There are several filters provided as part of this module, including some exciting experimental features such as CSS outlining. With some experimentation, you can fine-tune the configuration to get the maximum benefit in terms of page performance. In addition, make sure to configure caching and compression to get the maximum benefit out of your HTTP Server.
It's over four years later. Has anyone ever tried Pagespeed with Xenforo? I only wonder if it will break more of our forums than actually help them. I have some lower-traffic sites I may try it on, but don't know if it will do any good on a big board--all of this alleged gain in delivering the images is offset by increased CPU load.
Hmmm...I will install it on my smaller account and see how it goes. Agreed about the settings.
It's not like the big board I'm currently working on is suffering, but by the same token, I am trying to optimize everything to the fullest extent possible before anything bad happens. On this particular big board, we are running it on a single 4-core CPU dedicated server (with Elasticsearch), and with almost 2,000 visitors online (~600 logged-in members), our loads average around 1.50.
I can only imagine how much we'd be paying for hardware if we still had vB! It's a testament to how well XF performs under higher loads.
