Measuring performance impact of tracing a system under load

Hello everyone,

I would like to measure the overhead / performance impact that of tracing with DTrace has on a 
system under load. I'm looking for the right way to do it. Obviously, I should not be using DTrace 
to measure that in this situation. I could use other stats(7) tools but it does not seem. Measuring 
the impact indirectly sounds like a good idea (e.g., by looking at the throughput between two 
machines in a test lab as they transfer bytes from A to B in two scenarios: with active tracing and 
without). Are there any other options? Do you have any insights to share regarding measuring DTrace 
overhead?

I'd be grateful for all suggestions and pointers.


Best,
