Comment 142 for bug 119730

I'm having the same problem. Jaunty server (32bits version) with Zotac IONITX-A and one sata hdd. During large file copy CPU load goes to the roof and transfer rate drops down. Tested with cp, mc and samba. With samba (and gigabit ethernet) it starts from 65MB/s and drops down to 8-10MB/s within 2-3 seconds (at the same time cpu load goes up). It would be nice to have it sorted, otherwise I'm going to end up with Windows Home Server, because file transfer speed is unacceptable with this bug - and the machine was built to be a file server ;-(
I'm willing to try different things - if someone is willing to point me in the right direction.
