Symantec Endpoint Protection clients download large content updates that are almost the same size of full.zips instead of a smaller incremental delta update. This may result in higher than normal network bandwidth utilization between the manager and the clients. Additionally the disk space used by the manager increases with a greater number of files (SymDelta_xxx) and folders in "C:\Users\semsrv\AppData\Local\Temp\".
