Here's a screen shot of my Slic3r speeds tab. The speeds are the same as I use on my Prusa-Mendel
[attachment 22278 2013-12-03_0922.png]
So I'm doing perimeters at 50mm/s and infill at 80mm/s
But then the outermost (external) perimeter is set to 80% = 40mm/s
And the first layer speed is set to 50% so for the first layer the perimeters will be done at 25mm/s except for the external perimeter which will be at 20mm/s and the infill will be at 40mm/s.
These speeds are not the result of hours of experimentation so they may not be optimised. I got them from a forum post, (maybe by Nophead, not sure) and they worked quite well so I haven't messed with them.
I use the same speeds on my Prusa-Mendel It2.
