How do I get the Zune software to run better?

How does the Zune software run for everyone here? It runs like absolute dog poo on my computer that isn't THAT old and isn't THAT slow…at all….I have a huge library…around 15k-20k songs…is that why the software runs SO slow and sluggish? I mean it's getting to the point where I don't want to add anything to my zune because the software runs retarded on my computer. I've done recent virus checks and spyware checks and everything seems to be running alright…I'm almost considering getting a memory upgrade or perhaps even a new computer or laptop so I can have a good Zune software experience. Although I do not believe I should have to resort to spending more money to get a program to function properly.

Please help, and am I the only one??!
