I received this reply from Pair about my slow WP install, which apparently can be remedied by buying an extra software manager (access to the Software Installation Manager costs $2.95/month which is really kicker when you are already paying $360 a year for a webmaster account) :
Thank you for contacting pair Networks.
I see that you do not have the Software Installation Manager on your account, so I assume you installed WordPress manually. If the files you are trying to update were created manually by your username, WordPress may not be able to update them on its own. WordPress (or PHP in general) would try to do so as the username nobody. The username nobody would not be able to write to files owned by your username, and vice versa.
You can instruct WordPress to write to files with your username using php-cgiwrap. Our Knowledge Base explains how to set that up:
After you have PHP running as you username you may want to have us change ownership of any files owned by nobody to your username. That would allow PHP to write to them.
All fine and dandy, but the mods you have to make to php-cgi to fix my situation may not be worth the time it takes to make it. I hate messing around with base code.
