I am running a site with 30k+ users, but the site seems to top out with 100 people online, with connection issues and general slow loading. so i need to site completely optimized.
The site was reccently bought and there is a fair amount of messy files. the majority of the site is a phpbb forum and i would the forum to be optimized although this is not essential.
in total there are 30 or so files needing optimizing.
