Bug ID: 357465 Summary: nfs async write causes CPU to spike 100%, plasma to freeze, incorrect write speed. Sync works however Product: kio Version: unspecified Platform: Archlinux Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: nfs Assignee: unassigned-b...@kde.org Reporter: dougiem...@gmail.com Using a laptop with wireless connection to router KDE Plasma Version: 5.5.2 QT Version 5.5.1 Kernel Version: 4.4.0-1-MANJARO nfs-utils 1.3.3-3 fstab entry: 192.168.1.67:/volume1/share /home/doug/NAS nfs vers=4,noauto,user,noatime,x-systemd.device-timeout=10,timeo=14,intr,soft 0 0 Hi there, When copying large files to an nfs4 drive mounted as async the copying notification plasmoid freezes, cpu maxes out, dolphin freezes, write speed in the copying notification is incorrect and then disappears. This can be worked around by mounting as sync in fstab but this has slower read / writes. Can the async behaviour be fixed? In other desktop environments mounting as the default option async is not an issue. *strangely if it is mounted as async copying files over from the nfs drive to laptop does not seem to be a problem. Even the copy speed within the copying notification is correct. Reproducible: Always Steps to Reproduce: 1. mount nfs4 drive as async on wireless laptop connection 2. copy large file to nfs drive 3. -- You are receiving this mail because: You are watching all bug changes.
