High CPU usage on dwm.exe process
Citrix draws session windows using the system component called Desktop Window Manager (DWM)
Under high load, the component generates excessive CPU usage when rendering all the sessions at same time.
Solution
The Citrix plug-in does not require all the visual effects of Desktop Window Manager be enabled.
In order to allow a moderate use of resources without losing functionality, disable some visual effects features.
Under Windows run SystemPropertiesPerformance.exe program.
On the Visual Effects tab, select Custom option.
Just keep the option «Smooth edges of screen fonts» selected.
Image Hash or OCR fails on different machine resolution
Depending on the scaling configuration indicated in the server policy, or the default configuration of Citrix Receiver, the sessions will be scaled to adapt to the resolution of the client machine.
This adaptation of the session images causes the final image of the session to vary according to each machine with a difference in resolution to the machine on which the session was recorded.
This can prevent the Hash and OCR algorithms from working as expected.
Solution
To configure DPI scaling on Citrix Receiver:
- Right-click Citrix Receiver for Windows from the notification area.
- Select Advanced Preferences and click DPI settings.
The DPI settings dialog appears.
Change the settings to «No, use native resolution».
- Click Save.
- Restart the Citrix Receiver for Windows session for the changes to take effect.
In case you do not have access to that configuration screen, this is due to a policy indicated from the server.
It is possible to change the value of the configuration by changing a registry key.
Open regedit.exe and set the following key to disable dpi scaling:
Location : HKEY_CURRENT_USERSoftwareCitrixICA ClientDPI
Name : Enable_DPI
Data : dword:00000000
OutOfMemoryError: Java heap space error
JMeter has a set of default settings that allow the application to run without memory problems in most cases.
However, under some circumstances, an OutOfMemoryError can occur.
When the error occurs, this indicates that the configuration should be changed to consider the current memory usage.
Solution
In general, the OutOfMemoryError is due to the design of JMeter components and how they store information in the application memory for display.
One of the main memory consumers are the listeners.
1. First, let’s allocate as much memory as possible for 32-bit Java.
Locate the directory where jmeter.bat is located and edit it with a text editor.
Add after the line @echo the following line:
set HEAP=-Xms1024M -Xmx1024M -XX:MaxMetaspaceSize=256M
This allocates as much memory as possible to JMeter for the future runs.
Source: JMeter Wiki: JMeter keeps getting «Out of Memory» errors. What can I do?
2. Set a proper limit for the View Result Tree listener.
Locate user.properties file and open them with a text editor.
Add the following line to the configuration:
view.results.tree.max_results = 80
View Result Tree by default shows the last 500 items on the screen.
This consumes memory and can cause long tests to end up with an OutOfMemoryError.
Depending on the type of test you are running, the amount of information that JMeter stores may exceed the available memory.
The recommended setting limits only the last 80 results to remain visible to ensure that all memory is not consumed.
You can try increasing the value until you find the one best suited for the type of test you are running.
Source: JMeter View Results Tree documentation reference
Final notes
With the previous recommendations, in general, most of the problems with memory management in JMeter are solved.
In case they are not enough, there is also a good article available from BlazeMeter that tries to summarize other possible solutions to other possible causes of memory error.

JMeter has a set of default settings that allow the application to run without memory problems in most cases.
However, under some circumstances, an OutOfMemoryError can occur.
When the error occurs, this indicates that the configuration should be changed to consider the current memory usage.
Solution
In general, the OutOfMemoryError is due to the design of JMeter components and how they store information in the application memory for display.
One of the main memory consumers are the listeners.
1. First, let’s allocate as much memory as possible for 32-bit Java.
Locate the directory where jmeter.bat is located and edit it with a text editor.
Add after the line @echo the following line:
set HEAP=-Xms1024M -Xmx1024M -XX:MaxMetaspaceSize=256M
This allocates as much memory as possible to JMeter for the future runs.

2. Set a proper limit for the View Result Tree listener.
Locate user.properties file and open them with a text editor.
Add the following line to the configuration:
view.results.tree.max_results = 80
View Result Tree by default shows the last 500 items on the screen.
This consumes memory and can cause long tests to end up with an OutOfMemoryError.
Depending on the type of test you are running, the amount of information that JMeter stores may exceed the available memory.
The recommended setting limits only the last 80 results to remain visible to ensure that all memory is not consumed.
You can try increasing the value until you find the one best suited for the type of test you are running.

Final notes
With the previous recommendations, in general, most of the problems with memory management in JMeter are solved.
In case they are not enough, there is also a good article available from BlazeMeter that tries to summarize other possible solutions to other possible causes of memory error.

Hi,
Wfcrun32.exe is a process related to the Citrix. This should not be removed while running Citrix on your system and Like most applications it store data on your system’s registry and it is probably damaged by fragmentation or the accumulation of harmful
errors. so I recommend that you check your registry to identify errors hidden, and for your information when you Uninstall this applications it may leave registry keys that invade your registry. so I recommend that you scan your registry
