If 99% of apps are slower, that's everything I do on a computer! Yes it matters!
It doesn't matter for corporate environments perhaps. It does hell of matter for consumer facing web stuff, both the front end and the backend! 99% is a lot of stuff, so yes it does matter.
And the top reply (right now) is about 99% of the time is spent waiting for user input, and no, that isn't even true. A lot of that "input" is waiting on the network, and the number of requests for any application makes per unit time definitely scales with increasing code complexity.
But anyway, may be that makes a tenuous argument that most code does not care about performance, but again, if it's 99% of code, then yes it matters because it's my entire computer, and that's how we have machines that are faster than they've ever been yet they struggle to edit text compared to say emacs on pentium 4.
