there is one thing that kind of concerns me in your g-code info, however.. "; top_infill_extrusion_width = 0.6"
that really should not be set that high.. if you are trying to get better looking top fill, try reducing it slightly
i typically run 0.45 for top fill unless there are a lot of little details.. then i might go even lower..

Incognito, can you please post the ending part of the g-code for something - interested in the section that lists the different parameters used for the slicing...

but 50% of 50mm/s = 25 mm/s
and its still stuck at 10 mm/s

Try changing the external perimeters to 100% and see what speed you get. Thats how you can figure out how the math is working. Are your dimensions correct in that if you print a 20mm cube you get a 20mm cube?

i was printing all day yesterday and now i must have done something that now my gcode is stuck at 10 mm/s perimeter speed.. i tried both slic3r and cura with same results with perimeter speeds set @ 60 but when i put gcode in "gcodeviewer" it shows 10mm/s

using solidoodle 3 with repetier

Edit: first object was a single wall hollow box for calibration;
now if i try to slice it as a solid box with 10% infill, the perimeters print normal speeds but NOW infill gets stuck at 10 mm/s

You will need to post your layer and infill settings as well as speed settings for us to kn ow what you are doing.
