Microsoft Windows 7

Problem

You might encounter a performance issue with VSE 8.8 Patch 4 and certain applications. A comprehensive list is not available at this time; however, this article will be updated with application names as they become known.

The following table lists the applications known to exhibit symptoms of high CPU usage and/or sluggishness when running on a computer that is also running VSE 8.8 Patch 4:
Application Notes
DropBox.exe
Performance issues occur when the Dropbox application reads a file to sync it with Dropbox servers.
Dropbox detects a file modification and attempts to sync the file with Dropbox servers, even when the contents of the file might not have changed.
 
NOTE: This issue might also occur if you perform a DAT update and the scan cache is cleared. 
W3WP.exe No specific action by the application is required.

 

System Change

VSE 8.8 Patch 4 is installed.

Cause

Some processes might be configured to monitor for changes to a specific folder or file's contents.

When VSE 8.8 Patch 4 scans a file, the metadata of the file changes. This leads to the application performing additional work, which might appear as a high CPU symptom or performance lag to the user.

Solution

This issue is resolved in VSE 8.8 Patch 5.

Patches are cumulative; Technical Support recommends you install the latest one.
