For some reasons like PCI-DSS requirement we have to set the "Log Out Idle Representative After" to 15mn. It's very heavy for many teams like helpdesks because for each time all items spend many time to load. In our case, for 75000 servers and workstations, around 1:30mn.
The goal is to keep this timeout to 15mn but to keep in cache (for example) all items. Just need to reconnect without waiting items loading.
