Subject: Dynamics 2015 On-Premises slow in Internet Explorer

1.  Dynamics 2015 On-Premises slow in Internet Explorer

Posted 19 days ago

Hi everyone,

We started experiencing an issue recently and I am starting to spin my wheels.  Hopefully someone can point me in another direction.

What I Know:
- When loading entities in Internet Explorer 11, it is taking a long time to load sub-grids, the social pane, business process flow area, and other aspects of the page
    - By a long time I mean it takes over 20,000 ms, in other browsers it is taking 2,000 ms or less
- This is for any entity with any of those controls
- This does not occur in FireFox or Chrome
- We have 2015 On-Premises

What I have tried:
- Clearing IE cache & history
- Resetting IE via Internet Options
- Downgraded to IE 10
- Imaged a brand new machine with an older set of patches (approximately 2 - 3 months old) - Things work fine on IE in this machine
- Used Performance Center to compare load times (pretty much tells me what I already know)

What I assume:
- This is not a network nor server issue, otherwise other browsers would be affected.  Am I correct in assuming this?
- It is most likely a Windows client workstation update causing the issue, but haven't been able to prove it yet
- I would think if I downgraded (uninstalled/reinstalled) to IE 10 then it's not an IE update causing the issue

Has anyone else run into this or have any guesses as to what may be going on?  Thanks in advance for any help!

I don't know if this is the full answer, but IE11 is simply older, slower technology than the browsers you're testing against.  It will load CRM pages slower than Chrome, Firefox, or Edge.  There likely is something else going on as well, for as big a difference as you're talking about, but don't expect it to ever look like Chrome's performance.

We experienced the same thing about six months ago. One day users started complaining that things were really slow. I googled everything to find an answer. I rolled back patches and uninstalled extensions and add-ons. Nothing worked. It was particularly slow loading sub-grids (up to 7 seconds to finally load the screen!)
I even worked with our CRM partner and they said it was on our end. 
We finally switched everyone over to Chrome. No more complaints!

Do you have any 3rd party solutions installed?  We had one, also while on CRM 2015, that did this exact thing.

Also, though it shouldn't matter that much per browser I wouldn't think, can you clarify whether turbo forms are on or off?

To add to @Adam Robinson's post, check in your System Settings/General tab to see if the Legacy Forms setting needs to be toggled.

Did you profile the performance in IE11? That would tell you whatever is holding things up with BIG RED blocks.

We are also on CRM 2015 on-prem. I get a lot of end users complaining about CRM lag when they use IE. Just to add confirmation to the discussion: once they change to Chrome/Firefox, speeds increase substantially. I advise following the instructions in this link to compare performance in different browsers. The first step listed in this article I have used several times to troubleshoot performance. IE consistently performs poorer than Chrome.

Maybe you can "collapse" any subgrids/sections that don't need to render each time the page opens. If the user wants those to open they can "expand" the view/subgrid/charts.   Just show the data that is always needed.

Thanks for all of the replies!  I should have included our version in the original post:  7.0.2.53 and so we do not have the Legacy Forms option yet.

And I do understand and agree that Chrome and Firefox will be slightly faster than IE.  However a difference of 20 seconds cannot be account for by browser differences, and is not acceptable to the people using the system every day...or so they've told me, multiple times, the past few days :D

I'm working with our IT Operations team to look into any Group Policy rules that may be affecting this.  I would also look into our solutions, however I have not installed any new solutions recently and it is affecting our Out of the Box instance (absolutely no customization nor solutions have been added to that instance) and our development instance.

I sort of ruled out a Windows Server Update as I feel if it was a server issue it would affect all browsers.

I have tried rolling back Windows workstation/client Updates on my machine which has had no effect yet, but am halfheartedly continuing down that path with IT Ops.

Nothing appears off with the diagnostics test (attached), and I am looking into profiling the JavaScript right now.

Try using fiddler. The built-in crm test is kind of "misleading" as it only test the best case scenario (no plugins, rules and etc.)

Running fiddler on a user's machine while loading crm will definitely expose any latency issues.

Thanks Rex!

It looks like "LookupMruWebService.asmx" and "MessageBar.asmx" are the common culprits with very long load times.  Other .asmx, .aspx, and .ashx resources take quite a bit of time as well.  Could a .NET framework update cause an issue like this?

Another weird thing I noticed, the IE log has around 175 lines/results to it while the Chrome session log only has around 25 lines/results.

You're welcome.

It looks like this is a documented issue.

https://community.dynamics.com/crm/f/117/t/139033

Each browser has its own ways of logging things, even worse is that each browser has its own way of interpreting js (i.e. tabs is not an array in ie but is in chrome). 

You can try changing your chrome settings.

That's kind of what I was worried about: I had seen that first link you shared but the second appears to confirm it a bit more.  Just seems odd that it was working great for 5+ years in IE, then seemingly out of nowhere the performance takes a dive.  I would also think this would be a larger issue among the community.  There has to have been plenty of businesses using IE and On-Prem 2015; and still probably enough around to have see it more in various forums.

I'll keep plugging away and if anything helps I'll be sure to come back and update this post.

Ben 

Have you tried rebooting the server? I have heard of where patches will cause crm server performance to degrade but are resolved after a reboot.

I am suggesting this due to the fact that the problematic code belongs to Microsoft and there is really nothing we can do about those.

Yep, that was actually one of the first things we did (checked the application and sql servers, rebooted them, checked our out-of-the-box CRM instance running on an entirely different server, etc.)

KB4041681 was our salvation.  It was released on 10/10/17 and has worked for every user I tested with so far.
There is a specific line in there about fixing the form submission in Internet Explorer, I'm pretty sure that hits the nail on the head.

This updated took us from IE "update version" 11.0.46 (which is when the problem started) to 11.0.47 in case anyone else is interested or having this issue.

We just downloaded the latest update you mentioned and it worked for us as well. It removed the slowness of loading sub-grids in particular. However, since we have switched over to Chrome and everyone is happy, we will probably stay there.
