Summary
Versioning control task and PC navigation are very slow.
Error
Several ALM/PC tasks are very slow, Performance Center pages are very slow and Versioning Control activities take a long time to apply. Database and ALM/PC components are in AWS.
Cause
Database server was set in AWS under RDS SQL server instance. For now RDS is just supported for Oracle not for SQL.
Fix
Move the database to on-premise server or move the database to Amazon EC2 (Amazon Elastic Compute Cloud) outside the RDS policies. This fixed the slowness issue.
