I had the same and changed Vmin in
Marlin movement setup from 0 to 25mm/s ( my 1st layer speed )
Would be interesting to know if you can see a slow move command in your Gcode? I couldn't find any ridiculous slow moves in mine, but many G92 E0 lines to reset Extruder count.
@obewan
where is this
min time/layer option in slic3r?
PS: Nevermind, I found it in the filament/cooling section. But it was set to 10mm/s in my case and the "speed" I saw was more like 10mm/min...
