This program (mypaint) replicates traditional media pretty well and has brushes that imitate charcoal and the like - http://mypaint.intilinux.com/ I never had problems with lag as long as i wasnt using a HUGE canvas size and you can determine its dimensions if you dont want it to be infinite.
It's a free program also, so you can download it and use it with no problem as long as you like.
Hope thats some help :)
