Enter/Exit speeds

is there a possibility to speed up the taxiing onto the runway around curves or bends? The planes creep around those with 10 kts. The bend at Foxtrott Bravo in JFK looks like a high speed exit/entrance and the planes take their time while going 20 kts. Although cleared for takeoff they then tend to slow down before accelerating for takeoff

as always these are just suggestions/observations. I'm inpatient and if you guys think that this is the way it's supposed to be, I'm fine with that. You're doing a good job!
