when u say configuring the server do u mean tweaking it after it's up and running or is it the initial configuration how you set up the server itself first time?

I guess it must be the way how Ubbt is installed on the server rather than tweaking the configuration set up for server once it has been installed...

I am assuming that is the case.

Well there are a couple things that really do need to be adjusted on the server itself for best performance. That would be the webserver and mysql configurations. If either or both of those configurations aren't done properly, you could have a very nice server that performs very poorly.

The most users online on my board was 1042 and what's great is that the forum was running SUPER FAST during this peak time.

In the long run, if the site is to run for years and years then it would probably be good to split up the posts table so that a new one is created every year.
