It's the I/O scheduler and the vm. IOnice will help the former _when it comes out_. Dropping the swappiness kind of helps the latter; although there are numerous alternative tweaks appearing for that too. > > Yup.

Try loading it an external viewer and it will be 1000 times faster. If you're talking about it keeping the disk too busy on the other hand, that's I/O scheduling.
