Is there an enterprise software solution that you believe is better than vBulletin, especially in the resources department? I haven't found one, though I haven't looked in over a year.. In either windows or linux..
I know some big board's that moved to them from vb, such as
www.rcuniverse.com a long time ago, and they were much more resource intensive.. At least, the page load times were horrible until they added more equipment..
I'm not all that brand loyal, but vB has been the best that I have seen for a long time.. That and the hack community is incredible..
Always willing to learn more!
