Something I've been thinking about doing for a long time now is to have my forum run off of two servers... I'm hoping that with SMF my load will drop a lot, but various tech suppot reps have suggested that having 300-400 users constantly on a server is going to cause problems anyway ...

In that case, is it possible to have the forum mirrored?  Or basically having it share the CPU / MySQL load between two CPUs?  At two different hosts?

This is just a thought, but I'd like to hear some opinions on this...

sure, but it isn't something done by SMF. MySQL can do it. You can setup load balancers. I would test out what SMF does first.

MySQL can accomplish this task, however, I would examine your hardware/software setup as  mirroring the website is costly in both bandwidth and storage.

Easiest solution is getting a more powerful server.  A Dual Xeon with SCSI drives and at least a gig of ram should do fine.

maybe you should host the images and css somewhere else
or would that be a bad idea?

or just use a cluster of some coputers as your server

Putting MySQL and apache on 2 separate servers would be a start, then you don't have a single CPU processing apache and MySQL requests at the same time.  You just have to make sure the 2 machines have a 100Mbps connection between then (preferably plugged into the same switch)  You could take it a bit further and have 2 Web servers with mirrored data accessing a single database server.  My observation from watching my server load is that it's about 25% MySQL and 75% apache, so you could probably run 3 web servers off of a single database server (assuming they are all the same CPU type)

Hosting the images and css on a separate server helps also.  I do this with my forum, and it helps page generation times, because you do not have as many httpd threads running simultaneously on the same server.
