Bug ID: 440417 Summary: Really high CPU usage when many files are updated Product: dolphin Version: 21.04.0 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: dolphin-bugs-n...@kde.org Reporter: kde.acco...@lemaitre.re CC: kfm-de...@kde.org Target Milestone: --- SUMMARY When a folder with many files is opened within Dolphin and many files are modified, Dolphin uses 100% of a CPU core for a very long time (forever?). Dolphin is responding though. The problem stops when the folder is left. STEPS TO REPRODUCE 1. create a folder with a thousand empty files 2. open this folder with Dolphin 3. modify all the files with `touch *` OBSERVED RESULT Dolphin uses 100% CPU, and does not appear to stop (or maybe after a very long time). EXPECTED RESULT CPU usage should rise only for a small amount of time, if at all. SOFTWARE/OS VERSIONS Linux/KDE Plasma: NixOS/21.11pre KDE Plasma Version: 5.21.5 KDE Frameworks Version: 5.81.0 Qt Version: 5.15.2 Kernel Version: 5.10.48 ADDITIONAL INFORMATION I think that when multiple modification events reach Dolphin, it process every single events, even when they are redundant. If that is the case, a possible fix would be to ignore such events if there is already a modification event in the event queue. -- You are receiving this mail because: You are watching all bug changes.
