Google page speed indeed does show something. The fact that Swiftideas uses a CDN probably makes a lot of difference. But still your stylesheets require optimization according to Google:

I promise that if there was a detailed post written by one of the developers how to optimize these things (I don’t even use the Google maps API, what should I do?) there would be a lot less people complaining about the ‘speed of the theme’.
“It’s not us, it’s you but we’ll take a look” answers may sometimes be true, but they don’t help other users. A more detailed answer would be helpful to a lot of people 🙂
Have a great weekend.
