Application performance management solutions

I’m working on a Windows Vista computer, and let me tell, this thing is sssssllllloooowwww. I can’t begin to say how much time I have lost waiting for my computer to boot up completely, so I started looking for something to help make the transitions easier. My friend told me about application performance management solutions. I haven’t tried them yet, but I guess they make it so your computer software runs more smoothly.
