Under certain circumstances if option System > Settings > APS placeholders in provider panel is switched on, provider experiences increased load time of any APS-related screens in PCP.
In UI logs the following delay could be found:
[default task-67] DEBUG com.tbn.app.NavApi - 14857 ms [NavApi.handleNavigation]
During UI navigation resolving, OA retrieves properties of installed APS applications. In case of unoptimized database or slow performance of DB host, particular queries may need noticeable time to execute.
One of the slowest query could also be optimized. Request to the Engineering team was filled with ID APS-40210: "RQL query with specified property can be optimized".
It is also possible to configure database to optimize page reads from disk during sequential scan operations. But since it required direct database manipulations, please contact Odin Technical Support Team in order to acquire this workaround.
