Diagnosing slow RemoteApp performance

Can you show the code?  Need more info to help ...

This is how I resolve such complaints.

I would log on to the remote machine and run the app and check for performance. Most of the time the single user is sitting on a bad connection and the app is not slow but rather network. If you can work the remote app without any speed lag, please suggest the user to lower the RDP's color settings. That would free quite a bit of bandwidth and should resolve his problem.

Hi John Gates,

Sorry, the application consists of 1000s of lines.

Thanks, Abhigyan, for you comments.

I don't think just having a slow connection would explain operations that take a minute.

It does actually Leigh. No it is not the operation. The operation finishes as usual. It is the screen refreshing rate that creates the problem and user gets the screen refreshed with a time lag which makes him think that the application is slow.

Just ask him to lower the Colors option in Display tab of RDP (you get there by clicking on options) to lower say 16bit or 15 bit instead of 24 bit / 32 bit and then let us know.

If that doesn't solves the problem, you need to check the CPU usage when this particular operation is running. If that is high, use SQL Profiler to see which query is taking too much time and then have your developer optimize the query.

Thanks, Abhigyan.

I will get our customer to try the lower color settings.
Also, the Experience tab, will let him specify a slower connection.

You can try that. Usually the lowering of color resolution does the trick.

I'm testing the RemoteApp.

But I can't get to any of the settings such as Display and Experience.

Here's what I see when I click on "More details":

How does your user connect to this app?

Does he connects to Win2k8 server using remote desktop and then run's this utility or is this utility installed on his local machine and he runs from there?

The setting I talking about is for connecting to Win2k8 server using remote desktop.

Here is a screen shot.

The end user is given an .msi installer that installs a .rdp file and a shortcut to it.

That is how you run a RemoteApp - directly by clicking on the shortcut (which calls the .rdp file).  The user does not see the usual Remote Desktop login screen.

I just did a fresh install on another PC - the opening screen is identical to the screenshot above.

There's no way to access options such as Display and Experience.

Oh which means that the installer must be picking the settings from default.rdp.

You can locate the file in User Profile\Documents.

Check the following settings:

session bpp:

Or you can post the entire file here and I'll check.

Thanks to Abhigyan and Karrtik for your helpful suggestions.
