MSP interface performance slowness with Clarity due to environmental issue

Products

• Clarity PPM On Premise
• Clarity PPM SaaS

Issue/Introduction

You are seeing performance issues opening and saving Microsoft Project (MSP) Projects. This issue may be intermittent or consistent.

Some examples: 

• It can take more than 10 minutes to open a project via MSP interface. 
• When you try to save changes back to the project in Clarity, it is slow / clocking
• Additionally, you may also see a Target error referencing "Thread was being aborted" even after waiting more than 3 seconds after the project saves back to close the project. (See MSP: After saving project, project remains locked / target error for more details)

Environment

Release : All Supported Releases

Component : CLARITY MICROSOFT PROJECT (MSP)

Cause

This is due to an environment issue

Resolution

For intermittent issues, this points to an environmental issue such as a Network issue.

Both SaaS and On Premise

1. Ensure the clarity timeout is less than the SSO timeout
2. Check with your Network and SSO team to track the session and check for any issues such as time out inactivity 
3. Check the Network and SSO logs for any related issues/errors during the time of the issue
4. If you are seeing a certificate warning pop up message even after clicking Save to the certificate, see MSP/OWB - Certificate warning even after clicking "Save" (using proxy). The certificate check may slow down performance. 

On Premise

1. Enable sticky session persistence at the load balancer level. See also F5 Load Balancer timeout recommendations for Clarity
2. Check the following KB for additional setting recommendations: "Unable to Communicate to the PPM server" Intermittently Post SSO implementation
