LimeWire is written in the Java programming language. Rather than being written for a specific operating system, it is written for the Java virtual machine. This way, any operating system with such a machine, such as Windows, Mac OS X, or Linux can run it without modification. This usually comes with a slight performance overhead in memory and CPU usage. On a fairly modern computer, this will have no noticeable impact, but it can make an older computer slightly less responsive. Not that this is not the same thing as "making your computer slow." LimeWire will not affect performance when it is not running. Simply having it installed will not make your computer slower.
