First a little background Over the last year I've been using samba 3.x with great success. Client machines are in a Samba domain, performance is excellent over gigabit. Recently I've installed FUSE and have been using a fuse module EncFS to provide disk-level encryption. Samba over a mounted FUSE volume works. Read performance is good, and CPU utilization is modest. However the problem comes in for writing large amounts of data. Using a command line interface, copying 4GB or so of data takes an hour. Copying via the explorer interface hangs the machine after a period of time (the progress bar is also inaccurate). Has anyone attempted this configuration? Any suggestions on how to identify where the problem is (or solutions that pop to mind?) Any assistance is very much appreciated. -h Equipment specs System Configuration Fedora Core 2 2.6.10-1.9_FC2 Kernel Samba 3.0.11-1 made with rpmbuild Software Raid 5 (md) Hardware configuration P4 2.4Ghz 1GB Ram 4 200GB SATA drives using promise controller (sata_promise kernel module) Intel e1000 Gigabit adapter
