The *Begin() methods return a "handle" that will be passed to the *End()
methods. Have you considered to define a type for it rather than Object?
Something like an empty interface, just to signal the intent?
Yes I think so. A marker interface would suffice.
Do you have any performance measurement result that you can share?
I don't yet have any specific numbers - I'll try to get some. The testing I
have done indicates that the overhead is negligible. But it would be good to
confirm this.
refworkload is easy to run. You probably have talked with the
performance team. You can find out from them which benchmarks, if they
have any, are applicable for IO instrumentation.
