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? -----Original Message----- From: jeremi joslin [mailto:jeremi23@gmail.com] Sent: 02 October 2006 13:33 To: xwiki-users@objectweb.org Subject: Re: [xwiki-users] performance issue Hi; I don't think it's because of 2 or 3 people at the same time on one wiki. hundreds of persons are using wikis on XWiki.com at the same time as you. We had a problem recently with our mysql server, we lost a hard disk (one of our 4 HD of the Raid5, so no data lose). So we change the configuration of XWiki to go to send request to one of our slave server which is slower. We have asked to change this machine, so soon we will have a new one, for better performance. what do you mean by "the site fail to function" ? If you want better performance, we have a professionnal offer on other server with better support. for this contact luis@xwiki.com . jeremi On 10/2/06, wangwh@att.net <wangwh@att.net> wrote:

Hi, jeremi, My sites are on XWiki.com. I found that it is not the pages or objects on the site that matters, it is when 2 or 3 people are writing to pages the performance is affected. It happens when people are working on different pages on the same site. It is not easy for us to repeat and identify the cause, I wonder if other users have notice this. Sometimes, after speed loss, the site fail to function. Since multiple people working/writing to the same site is a part of using Wiki, we need to keep the sites perform reasonably good. Wei-hsing

Hi, How is your wiki? Is there is a lot of pages? Objects? Version? What is your XWiki version?

Hi, XWiki teams, I found that the wikis I need to write in are getting slower and slower, such as sustainagility and webagedefense. Quite inconvenient, especially when I am trying to introduce XWiki to new users. Other sites are responding quickly. Does writing/editing wiki pages causing troubles? Wei-hsing

It's a big problem for us, specially with the spam. when a robot is going on lots of wikis at the same time, it slow a lot XWiki.
