this setting is default on 0.02, you want me to change it to 0.45? that's a huge difference to the default settings isn't it?
Yup, basically the original setting doesn't do anything...
I believe it's like this >> at 0.45, with 4.5mm retraction a single piece in the filament can maximum go 10x over the "hobbed wheel" driving the filament. I's a nice starting point I think but you probably need to experiment a little with retraction intense prints.
What your printer can handle will depend on f.e. feeder type, temperature of the feeder (motor+wheel), material etc....

I sliced the model again in Cura 15.04.2 to check if this will work out.

it's already only on 30mm/sec, lower it to how much?
Default is 25mm/s, It is set this low because of grinding as Daid stated many moons ago.
