Re:performance problems with long wiki pages
18Kb should not be a problem. I cannot comment on the quality of the phpwiki converter as I have not used it before myself. Are there an unreasonable amount of wiki tags in your page, possiblly caused by the conversion? Another thing that caused problems to me in the past (<Tiki 1.7) is when start and end of some wiki tags are not properly ordered.
