    Hi,

    I'm using a WCF web service to load nodes on demand.
    The WCF web service method is called and complete in less thant 2 seconds, then it takes more thant 2 minutes for nodes (between 1 to 10 nodes) to be added to  the treeview !!!

    I'm using .Net 4 on Win7 x64 and IIS 7.5

    Any ideas/suggestions ?

    I really suspect a WCF configuration issue because when moving to ASMX web service, it works perfectly.

    I was using 3.5 and worked perfectly, I switched to 4.0 and it was very very slow.  I then used a asmx WebService instead of the AJAX-Enabled WCF Service and it worked again. Thanks Cedric

    James,

    I had the same symptoms you had: WCF service worked well with 3.5 but is incredibly slow with 4.0
