Re: [xwiki-users] performance issue

I'm not sure if this is the same issue that Wei-hsing (sorry if I spell that wrong) is having, but we've noticed on regular occasions our xwiki.com wiki's become unavailable altogether (no maintenance notices on the wiki's so assuming none being done at that time). Occasionally, we also notice even simple page loadtime is very slow for users that have just logged in. At other times, our speed is very good. A question, if I may: The xwiki.com sites appear to be working with a virtual wiki configuration (which is how the new wiki's are added dynamically I am guessing). Could it be that activity on a very resource-intensive xwiki.com wiki is affecting all the others?
