High CPU Utilization during Backup
Cause:
From 14740, below listed parameters will no longer be included in the command. As a result, when performing backups, 7-Zip utilizes a high number of CPU threads, leading to increased CPU usage.
- mmt - Sets number of CPU threads
- mmemuse - Sets a limit(in percentage) on memory usage (RAM) for compressing and decompressing.
Note: Prior to 14740, the 'mmt' parameter was configured as Half of Total CPU Threads and the 'mmemuse' parameter was set to 50%.
Fix:
The Older Configuration has been retained.
