Internet Explorer 8 slow with Active Directory Federation Services

    I have the ADFS scenarios depicted on
    http://technet.microsoft.com/en-us/library/cc779508(WS.10).aspx in the two
    sections both titled "Authenticating the user".

    When it comes to the steps 3 and 6 in the picture of the first
    "Authenticating the user" section and steps 5 and 7 in the picture of the
    second "Authenticating the user" section Internet explorer 8 causes 100% CPU
    load on one thread. The time it takes is proportional to the single thread
    processing power of the client CPU. On "old" clients it lasts so long that
    the requests fail due to timeouts. Even on modern clients 30 seconds delay
    occur. This occurs regardless of the operating system IE8 runs on.

    It works fine with Internet Explorer 6 and 7 and the latest public Platform
    Preview (Platform Preview 9.0.7745.6019/1.9.7745.6019) all perform well. I
    have tested this on several systems with clean installs of Windows XP, Vista,
    7 and Internet Explorer 6 to 9 Preview in all possible combinations. Other
    browsers perform fast with this as well.

    I think Microsofts Single sign on solution Active Directory Federation
    Services should be compatible with At the moment this is not the case.

    IE8 is Microsoft latest browser and Microsoft shouldn't moan about slow
    enterprise adoption of new technologies if enterprise products perform so
    bad. This needs to be fixed in IE8 asap! Even with IE9 Microsoft still has to
    support 2003 and XP clients and IE9 won't run on these!

    Kind regards.

    Hi,

    Please include details of your Compatibility View settings and security zone
    settings as these will have a bearing within an intranet.

    Regards.

    Re: Internet Explorer 8 slow with Active Directory Federation Serv

    All sites are in the Internet zone. 100% CPU load and timeouts on "old"
    clients occur if compatibility view mode is used and also if not.

    I also cannot touch every clients because they are in a few hundred
    different locations and are not centrally managed.

    Microsoft must fix this bug!

    Regards.
