I had similar issue. Saveing was usualy 0.2s but in some cases it was takeing aprox 4-6s.

What was done:
- click green "save" button
- button goes gray with spinner and text "saving"
- when done buttons goes green with "done"

Progress bar is nice solution... but only when you are able to determine the end of process.

Your loading is overwhelming. But still it is good to show it if it takes time, maybe not so big. Also a lot of things happens in the top: yellow bar disappears, orange notify goes down and "loading" disappears - like in action movie:)
