Using Cloud Connect with Client-side Cache Enabled
In high latency environments, performance can be affected by the amount of data that needs to be transferred between P6 Professional and the P6 database. Enabling client-side cache can help to improve performance in these high latency environments by improving the speed of the most frequent operations: adding, deleting, and updating activities.
While you work in P6 Professional you are working in the local cache database which provides increased performance over connecting to the Cloud Connect database directly. In the background, the Primavera Cache Service continues to synchronize global data and data for the projects you are working in between the local cache database and the Cloud Connect database.
When you log in to a Cloud Connect database, Primavera.CacheService.exe starts P6 Professional and then minimizes, to run in the status tray. Primavera.CacheService.exe continues to run even after you close P6 Professional so that the service can continue to synchronize the local cache databases with the relevant Cloud Connect databases. This allows P6 Professional to start more quickly the next time you connect. If the Primavera.CacheService.exe is running in the status tray, you can right click on it and select Start P6 Professional to restart P6 Professional. You can maximize Primavera.CacheService.exe at any time by right-clicking on the icon in the status tray and selecting Show.
Note: The first time you connect to a Cloud Connect database, or if you mark the Reinitialize local cache option when connecting, a large amount of data will be downloaded from the Cloud Connect database and stored in the local cache. This can mean that P6 Professional takes longer to open. Some changes to your security profile also trigger a refresh of the local cache which will cause P6 Professional to take longer to open. In all these cases, once P6 Professional opens, performance will be improved.
To optimize the amount of data that flows between P6 Professional on your desktop and the P6 server, ensure that you have a stable, wired connection to the P6 server and follow the guidelines described in this section.
