It is recommended that you use at least 2GB heap size for your installation. The optimal memory setting for your installation will largely depend on:
- The amount of sync activity; more syncs will require more memory.
- The number of sync changes per sync. Syncing files and folders consume memory until the sync is complete. After syncing is complete, the memory is reclaimed. By default, the client syncs every 5 minutes, but this needs to account for users going offline for long periods of time. So, the calculation must account for this time.
- The setting of the sync.cache.expiryTime property in the config.yml file. The default value is 30s. This will reclaim the memory used by a sync after 30s if it hasn’t already been reclaimed.
