    Hi guys,<o:p></o:p>



    I have a deployment where I have 3 servers, and it’s
    working fine, but sometimes when you open crm for the first time it takes
    around 10-15 sec, and it’s like when it is cashed, it works fine, but if you
    leave machine for like 30 min and click on contacts it takes again 10-15 sec.<o:p></o:p>

    As far I can see on server, everything is fine with
    CPU+RAM and there is only like 10 users using it right now.

    They all connect via web-browser.<o:p></o:p>

    any idea?<o:p></o:p>

    Unfortunately, there could be a thousand causes for the poor performance of a CRM deployment, so it's quite difficult to troubleshoot through a forum. Have you tried following the guidance offered in this white paper from Microsoft: https://www.microsoft.com/download/en/details.aspx?id=27139?

    I would use Fiddler2 to monitor the web requests and see if all of the JavaScript and other web resources are being returned on each request.  That is the issue I have run in to the most with performance is that CRM returns VARY: * in the response which tells IE to not cache the file. Without caching you may see two dozen requests and over a MB of data transmitted when you open a record.  I have a similar issue right now with going offline on Outlook, it doesn't seem to make sense that to view 40 leads we need to transmit 45mb of data - but maybe thats just me.

    An addition to Carsten post, here is an older article how to enable Kerberos. Related with the same concept reducing the authentication round-trips.
