According to the project site: http://gwenole.beauchesne.info/projects/sheepshaver/ it is running applications at about 1/8 native speed. If you have one of the lastest dual-core Macs, that is many times faster than the original machines that most OS 9 applications were designed to run on, that mostly makes up for the speed hit.
