I assume this is due to the high rate that the Backup GUI is updating the number of packages found (the number changes so fast I can't read the right-most digits). You could cut in half the CPU load on the system that is due to running System Backup by simply updating the GUI much less often. Note: Perhaps the rate at which System Backup finds packages on my system is unusually high since the system is installed on a vary fast solid-state drive. Reproducible: Always Steps to Reproduce: 1. Run top or htop, observe the CPU load on the system, especially the Xorg process, which should be at nearly zero CPU usage. 2. Start the System Backup GUI. 3. Click the "Create Backup" button. 4. Observe the "Modified Files" and "Total Size" fields update their values very fast (too fast to read). 5. Back in top, observe the Xorg process using nearly as much CPU as the "y2base backup gtk" process. 6. When the backup finishes, observe the CPU usage of Xorg return to nearly zero. So, whatever was causing Xorg to use so much CPU, was clearly related to the System Backup GUI. Actual Results: CPU usage on my dual-core system is nearly 100%. Expected Results: I expected CPU usage to only be about 50% (one core, not two). At least until the "Create package archives" phase starts (running bzip). Suggested change: update the "Modified Files" and "Total Size" values in the GUI much less often. System is installed on a solid-state drive, so Yast discovers packages at a very high rate during backup. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
