I'm redesigning my site using wordpress, and looking to switch webhosts as well (currently on yahoo). My site is pretty low traffic, and I don't expect that to change drastically in the near future, so I'm not really concerned about bandwidth or traffic spikes. On the other hand, the site is somewhat graphic and plug-in heavy, as it mostly features my portfolio with NextGen and several related plugins.
I'm wondering if it makes sense for me to go with a VPS because of the need for speed, or if it is overkill to spend 4x as much money for a low traffic site. Does anyone know about what the difference is in speed for shared vs VPS (I'm looking at hostgator as the likely choice)? Is VPS just a little faster? Twice as fast? 10x as fast?
Also a little unclear on the support and configuration issue. I'm a designer, not a sys admin, so the "administer your own server" aspect makes me a bit nervous...on the other hand, if VPS means better support, and someone who knows what they're doing going in and editing the .htaccess and php.ini files instead of me, then that's a plus.
Also wondering if anyone has any feedback regarding Virtuozzo. Hostgator doesn't offer cPanel at the lowest level of VPS, only Virtuozzo.
