The last days i searching to make DNN faster, because after a upgrade from DNN 6.1.5 to 6.2.7 and a upgrade of dnnckeditor to version 2.0.4.
Site administrators find it very slow on saving some things.
I can find out some intersting thinks :
If you edit a item (not in a popup, from the annoncment module for exemple) and save it.
And you analyse it with fidller, you see 3 http/html requests.
1) click edit item
return code : 200 ok
2) click save item
return code 302 / redirect
3) show articles
return code 200 ok
What is abnormal to me is step 2.
Why is te content returned by a redirect so big ?
Fiddler show me there arre 2 html send in the content.
A html tag with the reirection (that normal) + a html tag with the page content (not normal and 5 times bigger then the other requests)
I check this on dotnetnuke.com and it hapend also.
