218 - Wie kann ich dem Desktop-Client mehr Arbeitsspeicher (RAM) zuweisen?

For users with many files and a total data volume greater than (>) 100 GB, synchronization performance can be improved by increasing the memory allocation of the LRZ Sync+Share client.

In the following configuration files, the numerical value can be adjusted for the argument -XmxVALUEm. For improvement, we recommend increasing the maximum memory allocation to -Xmx4096m (4096 MB → 4 GB).
