There are performance issues when trying to save an MPP file to Clarity via the MSP Integration addin. Save may take over 30 minutes.
Release : 16.0.0
The logDirectory and tmpDirectory values are configured to point to a network share, which increases the save time performance.
From your desktop launch Regedit.
Browse to: Computer\HKEY_CURRENT_USER\SOFTWARE\Niku\MSPInterface
Review the values for logDirectory and tmpDirectory. Changing the values to the local PC may improve performance if there's a network restriction issue involved.
