That depends on how often you are creating tasklets.
It is only the startup overhead. Later on, your tasklet
runs at the same speed as everything else, the task
switching time is not dependent from that.
On the other hand, if you are creating very short
running tasklets all the time for just a few instructions,
the overhead might become more visible. But I wouldn't
care, this is *all* very fast stuff.
