Bug#600871: nfs-common: Very slow and unreliable performance of GUI(KDE) when /home nfs mounted
Oleksiy Vasylyuk reported severe performance degradation of KDE on an NFS client on Linux 2.6.26 after upgrading nfs-utils from version 1.1.2 to 1.2.2. Some additional details are logged at http://bugs.debian.org/600871. Does anyone recognise this problem, or can someone suggest how to investigate further?
