I have seen some forums which have installed xenforo in the root directory of their domains (ie, at www*domainname*com)
And others like this one which have put the forum in a /community or /forum sub-directory (ie, www*domainname*com/community/)
And yet others which have installed in a sub-domain such forum*domainname*com
How does each installation type affect the SAFETY and SPEED / PERFORMANCE of xenForo and it's themes and add-ons especially as the forum grown in number of database querries?
Does it affect the functioning of mod_rewrite scripts as well?
