I can't really say if that is your problem or not without looking at it (and even if I was looking at it, I wouldn't be able to tell you but somebody else probably could if they actually saw it). Do you have any calculated dimensions? I had a huge calculated dimension that made the whole sheet incredibly slow to the point where you really couldn't even click on anything. Once I figured out what I was doing and I put it in an expression instead, everything was fine.</P></BODY></HTML> Tue, 08 Mar 2011 22:59:58 GMT https://community.qlik.com/t5/QlikView/Performance-Issues/m-p/241939#M92330 2011-03-08T22:59:58Z
