DotnetNuke Problem: Pages are not render properly and What need to do Enhance Performance

Hi,
I have deployed the site as CityOptics.co.uk ,

Pages are not render properly when try to Open pages quickly one after another.

WhenI open page it open correctly , but when i try to open pages quickly (by right click on tab and open 4 to 5 page s together)
1. it generate error ( refer file Error-OnPageLoad.jpg)
or
2. generate page without menu (file BlankMenu.jpg)
or
3.
redirect to Home page
or
4.
generate Error on resource files.( cache files )

This is realy irritating to me as i am not able to identify why this is happning.
Any idea whythis is hapning and what need to resolve these ?
One reason might be speed of the application , at local application it is working fine.

Apart from this i am alos working on Performance Issue.
can any one please suggest for perfomance, and How can reduce size of Page. (ie. How can i remove ScriptResource.axd or ScriptResource.js , webresource.axd etc) or can I disable Ajax from DNN site.

Error Files attached.
1 .BlankMenu
2.Error-OnPageLoad</BLOCKQUOTE>
Thanks

Hi Nikhil,
DNN is indeed very resource heavy.
You can Google for tips on how to lighten it up a bit, especially the official support site.

One of the things you should do now is increase the Quotas.
