The easiest way is to upgrade to a virtual dedicated server. As mentioned previously a virtual dedicated server allows you to run your sites as if it had its own server "dedicated", except that it is actually cheaper because you only use a portion of a server is divided into multiple virtual dedicated servers.
Tulad ng nabanggit sa nakaraang isang virtual server ng nakalaang ay nagbibigay-daan sa mong patakbuhin ang iyong site na kung ito ay sariling server nito "nakatuon", maliban na ito ay aktwal na mas mura dahil ka lamang gumamit ng isang bahagi ng isang server ay nahahati sa maramihang mga virtual dedikadong server.
