    Recently setup public facing FBA site, authenticated using AD via LDAP over SSL, takes morethan 50 seconds for most of the pages. But this issue is not consistent. And this issue is not just happening at the moring (warm-up script is already running). Is there any suggestion to improve login time? Is there any "tool" available at AD or SharePoint - to find how much time AD has taken to authenticate the user?

    Hi Justin,

    By default logging of domain user actions (apply of group policies, profile loading etc.) are not being logged anywhere in retail builds of “Windows” operating system. Despite that, that log information is essential when troubleshooting slow logons problems, so you can enable the logging doing those steps:

    1. Open REGEDIT
    2. Navigate to HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionWinlogon
    3. Create a DWORD (DWORD (32-bit) on x64 OSes) named UserEnvDebugLevel
    4. Enter hex value 0×00030002.
    5. Close REGEDIT

    Also, a tool that I always use is Fiddler with the NeXpert Plugin. It will provide how long each post, get, gif, etc took along with if any calls had to be made more than once...
