Hi Chaos,

Currently there don't have benchmark on ktap, I will add a item into todo list.

I guess you are concern about the overhead or performance of ktap interpreter,
I cannot give you accurate performance number, but long times ago, I tested ktap
performance using sembench, then compare the sembench output number with no ktap
monitoring, the results show that ktap doesn't impact results too much, nearly
5%-10% loss, note that at that time ktap was not optimized.

In future, ktap will take serious on performance, I considered use some JIT 
but not decided, just for your information.
