Don't make the mistake of trusting rackspace. The support is a joke, and they'll convince you to upgrade for site speed, only...展开
to tell you after that "partitioning the expanding disk space is not included in the upgrade, so we will charge you for that service."
WP Engine is AMAZING. Our site sped up immediately, it's so much cheaper, and the support is incredible. I have yet to feel that they've lived up to less than they guaranteed they would.
