Dnn4.5.5 should have done a lot of work in terms of performance. The above hostsetting Page's performance settings are not available in dnn3x (at least in 4.3.5 I am familiar.
1. page state persistence. I don't know how to translate it, but I know what it does. the viewstate of the page is saved to the page or memory. if the page is selected, the default Asp.net method is saved to the page. If the memory is selected, it is saved to the memory. we will find that
<Input type = "hidden" name = "_ viewstate" id ="
_ Viewstate "value =" "/>
That is to say, the viewstate of the page is empty.
2. Module cache method (not viewed yetCodeImplementation, to be learned, and later)
3. Run settings
Modulecontroller. VB
Public Function gettabmodules () Function Gettabmodules ( Byval Tabid As Integer ) As Dictionary ( Integer , Moduleinfo)
Dim Key As String = String . Format (datacache. tabmodulecachekey, Tabid)
' First check the tab Cache
Dim Modules As Dictionary ( Integer , Moduleinfo) = Trycast (datacache. getpersistentcacheitem (key, GetType (Dictionary ( Integer , Moduleinfo), Dictionary ( Integer , Moduleinfo ))
If Modules Is Nothing Then
' Tabmodule caching settings
Dim Timeout As Int32 = Datacache. tabmodulecachetimeout * Convert. toint32 (common. globals. performancesetting)
' Get modules form database
Modules = Fillmoduleinfodictionary (dataprovider. instance (). gettabmodules (Tabid ))
' Cache tabs
If Timeout > 0 Then
Datacache. setcache (Key, modules, timespan. fromminutes (timeout ), True )
End If
End If
Return Modules
End Function
Tabcontroller. VB
Public Function gettabsbyportal () Function Gettabsbyportal ( Byval Portalid As Integer ) As Dictionary ( Integer , Tabinfo)
Dim Key As String = String . Format (datacache. tabcachekey, portalid)
' First check the tab Cache
Dim Tabs As Dictionary ( Integer , Tabinfo) = Trycast (datacache. getpersistentcacheitem (key, GetType (Dictionary ( Integer , Tabinfo), Dictionary ( Integer , Tabinfo ))
If Tabs Is Nothing Then
' Tab caching settings
Dim Timeout As Int32 = Datacache. tabcachetimeout * Convert. toint32 (common. globals. performancesetting)
' Get tabs form database
Tabs = Filltabinfodictionary (dataprovider. instance (). gettabs (portalid ))
' Cache tabs
If Timeout > 0 Then
Datacache. setcache (Key, tabs, timespan. fromminutes (timeout ), True )
End If
End If
Return Tabs
End Function
4. Authorized Cache
File: dotnetnuke_04.05.05_source \ website \ default. aspx. VB
If Request. isauthenticated = True Then
' Set Client Side page caching for Authenticated Users
If Convert. tostring (portalsettings. hostsettings ( " Authenticatedcacheability " )) <> "" Then
Select Case Convert. tostring (portalsettings. hostsettings ( " Authenticatedcacheability " ))
Case " 0 " : Response. cache. setcacheability (httpcacheability. nocache)
Case " 1 " : Response. cache. setcacheability (httpcacheability. Private)
Case " 2 " : Response. cache. setcacheability (httpcacheability. Public)
Case " 3 " : Response. cache. setcacheability (httpcacheability. Server)
Case " 4 " : Response. cache. setcacheability (httpcacheability. serverandnocache)
Case " 5 " : Response. cache. setcacheability (httpcacheability. serverandprivate)
End Select
Else
Response. cache. setcacheability (httpcacheability. serverandnocache)
End If
End If
Why is the above source code set like this? I don't understand it. Please give me some advice.

5. Compression setting: The compressionmodule built in dnn
<Let your dnn fly, super acceleration> http://www.cnreds.com/Default.aspx? Tabid = 60 & articles id = 185
Article MediumThe compressionmodule cannot be used normally in dnn4.5. The actual dnn has built in this function.
6. Use whitespace Filter.
We will introduce how to optimize the system in the previous sections.
PS: the ranking is 2000.
