I read this blog post Microsoft Dynamics CRM 2011, related Microsoft Windows Internet Explorer memory leaks, and Windows / Microsoft Update from the blog Dynamic CRM in the field which has some quality posts and I recommend you subscribe to the blog, written by Greg Nichols – Microsoft Dynamics CRM Premier Field Engineering
When I read the title of the post I thought it was important enough to help publicise the fix. When you working with a customer who is experiencing a slow CRM you try anything and everything to try and boost performance.
It can extremely frustrating because one installation can be fine and you do exactly the same thing on the next installation and it’s slow but there are lots of parts to CRM 2011 and SQL databases can always be tweaked to perform better.
I haven’t experienced any memory leaks yet (or I haven’t noticed anyway) but the blog explains about a leak in Internet explorer.
I can’t really summarise the blog post so read the whole thing here but I will copy some various parts
Please note: Windows client servicing, via Windows Update or WSUS (Windows Server Update Services) + SCCM (System Center Configuration Manager) is also vital. We’ve identified a fix that can potentially help with Internet Explorer memory leaks. This fix was pushed through Windows Update via MS10-090: Cumulative security update for Internet Explorer. It was released earlier this year and is likely already on your client machines. HOWEVER: the fix I’m referencing here is registry enabled, so to receive the benefits of this fix, you need to add the registry keys mentioned in the associated Microsoft Knowledge Base article:
The registry changes needed to activate the fix are described in this Knowledge Base article, and for large enterprises, these registry keys are generally pushed by GPO (Group Policy Objects) or other means.
In any case, I heartily recommend that you assure MS 10-090 is installed on your client machines and the KB 975736 fix enabled if you are still experiencing Internet Explorer-related memory leaks when the latest CRM 2011 Server Update Rollup (as of this writing, Update Rollup 5) is installed.
