[Swift-devel] Is there a way to make swift send 256 tasks at a time

Hi,

For now, I understand how swift decide how many tasks send to one site 
at a time:
let T = 100
let B = 2.0 * log(T) / pi
let C = 0.2
let tscore = e^(B * atan(C * score))
let number-of-jobs = 1 + (jobThrottle * tscore)
T is initial score.

I am wondering  that , is there a way for swift to set a constant number 
of jobs, say 256 at a time to 1 site?
The reason I am asking this is that we could avoid the slow start 
period, thus improve the efficiency. Thanks

best wishes
