Apache. It's running really slow right now because with only 128 megs of ram, I'm dipping into my swap file a bit. Hopefully this will be cleared up soon.
Average monthly bandwidth usage = 10 gigs/month
What I am entitled to on this dedicated server = 50 gigs/month
As I said, this is a very entry level server. Basically, I wanted to get my hands on something that would let me move off of a shared server. However, this is a temporary solution until daniweb starts earning me money (via google ads, etc.) and making it worth the investment.
This is just a hobby site, of course, but I would at least like to make back as much as I put into the site. :)
