Starting with Peer Global File Service v5.2, the maximum memory allocated to the services of the Peer Management Center (PMC) default to between 2 GB and 4 GB, up from between 1GB and 2GB in previous versions. These defaults are generally sufficient for basic file collaboration, synchronization, and replication.  However, it may be necessary to increase memory allocation for heavier workloads (e.g., VDI/profile synchronization) or under the following conditions:  

- The memory allocated to the PMC Client (PL-Hub.exe, only available on Windows-based PMC servers) may need to be increased if you are dealing with many quarantined files or many jobs in the PMC's UI (e.g., tens – hundreds+ jobs, hundreds - thousands+ quarantines).
- The memory allocated to the PMC Web Service (PL-Hub-Web-Service) may need to be increased if the PMC's Web Client is being used to manage many quarantined files or many jobs, or if you have many admins/users accessing the PMC's Web Client.
- The memory allocated to the Peer Management Broker (PL-Broker) and the Peer Management Center Service (PL-Hub-Service) may need to be increased to improve performance when dealing with heavy real-time activity and large backlogs.  The Broker will typically consume about half the amount of memory that the Peer Management Center Service does.
- We recommend using a 1:4 ratio for the memory allocations of the PMC Client/PMC Web Service compared to the Peer Management Center Service and a 1:2 ratio for the Peer Management Broker compared to the Peer Management Center Service.
