Increased Process Execution Duration

Observed Behavior

Process execution takes almost twice as long when Studio is installed from UiPathStudioSetup.exe (Community Edition), compared to UiPathStudio.msi (Enterprise Edition). The issue occurs on Studio 2021.10 and above.

Cause

Studio Community Edition is installed in %localappdata%\UiPath, which is not a trusted location by Windows Defender. This means that every time a log file is created, Windows Defender starts to scan it, which prolongs the process execution.

The scenario does not apply to Studio Enterprise Edition, because the installation folder (%ProgramFiles%\UiPath) is trusted by Windows Defender, and thus not scanned every time a log file is created during the execution of a process.

Solution

Adding the Studio Community Edition installation folder (%localappdata%\UiPath) on the Windows Defender exclusion list means log files created during the process execution are no longer scanned on the spot. To add a folder on the Windows Defender exclusion list, you need to perform the following steps:

Click the Windows Start button, then search for Virus & threat protection and open it.
Access the Virus & threat protection settings page.
Access the Add or remove exclusions page from the Exclusions section.
Click the Add an exclusion button, then choose Folder from the drop-down menu.
Navigate to the %localappdata%\UiPath folder, then click the Select Folder button. Please note that Administrator rights are required to add a folder on the exclusion list.
