I'm developing high load solution with final version of asp.net mvc. Recently our team noticed, that most of the time that takes a server to response to client is devoted to page rendering. Simple time-schedule looks like this:
Page start - 1.8608363s
Render module 1140/Modules/Owners start - 1.86859s
Render module 1140/Modules/Owners Complete - 1.9081751s
Render module 829/Modules/Links start - 1.9081788s
Render module 829/Modules/Links Complete - 2.3380648s
Render module 1036/Modules/Advertisement start - 2.3459101s
Render module 1036/Modules/Advertisement Complete - 2.3482298s
Render module 1110/Modules/Goodies start - 2.3482322s
Render module 1110/Modules/Goodies Complete - 2.6300744s
Render module 1004/Modules/TopicLinks start - 2.6300784s
Render module 1004/Modules/TopicLinks Complete - 3.8852529s
Render module 1048/Modules/News start - 3.8927697s
Render module 1048/Modules/News Complete - 4.4958795s
Render module 1128/Modules/SuggestedLinks start - 4.4958832s
Render module 1128/Modules/SuggestedLinks Complete - 4.5704227s
Page end - 4.5711193s
TopicMainMenuPages start - 4.5717661s
TopicMainMenuPages End - 4.571974s
Render Finished - 4.6185852s
What could be a reason for such a slow rendering? Is that for oftentimes using of partial render during single request?
