Still a problem in Ubuntu Jaunty with all filesystems converted to EXT4. Copying 6-7 GB from one place on a partition to another place on the same partition (i.e. duplicating the data on the same harddrive) results in extreme I/O latencies, and things like starting up Firefox while copy operation is going is totally impossible. It seems that latency on Linux suffers badly whenever there is heavy writing, the in I/O scheduler is not up for the job of providing an OK desktop experience.
