About performance tuning of optimized duplication and replication for MSDP cloud
When an optimized duplication job or AIR job is initiated from a cloud LSU to a local LSU or another cloud LSU, for high latency network, tune the MaxPredownloadBatchCount parameter on the source side to improve the performance.
The MaxPredownloadBatchCount parameter in the agent.cfg file is the global setting for all cloud LSU. You can tune this parameter to control the concurrency of download from the cloud LSU to improve the performance.
The range of this parameter is from 0 to 100. By default, the value is 20. If the value is set to 0, the concurrent download is disabled.
The agent.cfg file resides in the following directory on MSDP storage server:
UNIX: <storage_path>/etc/puredisk
