I moved my wpmu site from a shared host to VPS ( MT(dv) ), I changed the domain name as well, I found the site will get problem if I define VPS to "yes" in wp-config.php, but changed it to "NO" will be ok. I think that is because my site was migrated from a shared hosting.
I just wonder if I define VPS to "NO" on a actaul VPS hosting"
"define('VHOST', 'no');"
will it impact the performance of wpmu on my current VPS hosting? I mean this VPS is much more expensive than the previous shared hosting, if wpmu could not benifit from it maximally, that will be a big pity.
