Speedup:
	How much faster is the program when using multiple threads?

Things that cause problems with speedup:
	Caching, and large amounts of memory access
		Especially writing from multiple threads
	Single-threaded sections that have to be locked
	Network or hard drive use

A task that's pretty good:
	Applying image filters!
	A simple one:  Just change channels around or something
	More complicated:  Can we bring out the edges?
