CRM Customer Engagement - sporadic very slow performance

Posted on by

Hi all,

As the subject mentions, we are experiencing sporadic very slow performance using D365 CRM Customer Engagement v9 online.  After initial support ticket has been opened, Microsoft is claiming it is because we have a very small number of users and therefore when we login (for instance), it doesn't know which server to use and one time may use serverA and later in the day use serverB.  Each time we use a different server, there are a lot of cache files that need to be downloaded.  This sometimes takes 80 seconds or so just to login and have the home page display.  Microsoft claims that as we add more users, the servers "will learn" which server to direct us too and performance will increase.  By using Fiddler trace logs I can see where when we do hit the same server as the previous login, our login time is between 3-6 seconds which is perfectly acceptable.  My question is this:  Has anyone else experienced this with a small number of users (5 users, only 2 logging in every day) and then saw an increase in login as their user-base grew?  We are on an old CRM 4.0 instance now and wanting to migrate to the new version, but not if we cannot get the performance we need out of it.  Eventually, we would be over 500 users.  I would be interested very much in hearing anyone who had personal experience with a similar situation.  I cannot imagine that large companies with a great number of users are experiencing the same performance issues as we are. 

PS - we do have some small customizations, but nothing until you get into Accounts which no one is using as their startup page.

Thanks in advance to anyone who can respond with similar experiences.

    I can relate to your frustration.. I have had my share of unsatisfied calls with MS folks over the years. Two things you can do now:

    1. Generally they have some kind of mechanism to escalate the matter..try that

    2. Have a field service agent inspect your infra/scenario in detail.. beware this will be a paid exercise.

    Thanks for the feedback... but we have covered all of those bases and many more.  I have had this ticket open for quite a while with Tech Support and when they finally gave me an answer, the above is what they said.  I have tried multiple browsers, multiple networks (work is the fastest by far), and we are not loading a customized form.  Everything Tech Support could think of has been tested.  Their answer just doesn't seem to make any sense to us.

    In my personal opinion I have not seen pages taking 80 seconds to load, even if the user count is <10. Having said that, performance depends on many factors:

    1. How your authentication is configured

    2. Level of customization

    3. Latency

    4. etc etc

    Some realistic check you can peroform at your end:

    1. Check the configuration of your client machine

    2. Use Chrome borwser and see the difference

    3. Check the load time of an uncustomized form

    4. Try to access your application from different location- perhaps home network with better bandwidth

    This will give you some idea where things are going wrong.

    Hope this helps !
