Thank you for comments, it should load faster with optimised images and file caching enabled(first image only is almost 0,5 Mb), I can make static generated page that looks same way (almost identical or however you like it
), depends on needs.
Any system have flaws and advantages, just some of them:
Static pages are somewhat faster to generate or lets say need less server resources, simpler and easier to maintain, no database and no php makes them harder to hack. But
, any changes in content need manual code change, and if there is many pages it may be pain just to add new menu item...
Content Management System is all point and click, easy to add news or change content, but
need to be updated regularly (joomla have auto update system for core and plugins), with caching pages get generated only once in a while and that saves some server resources. Of course CMS need database and php running on server (same as this forum and wiki).
I have joomla in few sites and did not experience any bugs or glitches yet. It has backend with user login and any member with permission can add content.
So basically all comes to what freeorion needs, if you plan to regularly change content, add news, write stories or similar go for CMS, if not then static pages are best.
But, with any CMS I'd always be most worried about maintenence after install, if the person/people that know it well become unavailable, how easy is it to update and/or how insecure is it/likely to be if not updated? Had some serious problems with unmaintained Wordpress installs in the past and I've no idea how good Joomla is at security.
My hosting company have cpanel with softaculous and that software creates backup and updates joomla automatically as new version is out and send email notification. I don't know if that is the case with freeorion hosting, as I said before joomla have built in updater, and as soon as you login in administration it is offering to update itself.
