Thanks Chris. In fact, those methods was the kind of thing I was looking for
:)

I am not sure if I understood. In our benchmarks, we have a list of samples
and each sample is at the same time an array of objects that we
serialize/materialize. For each sample we create instantiate a serializer
and a materializer.

I understood now that we should reuse the same serializer/materialize
instance for all samples?  if true, why I don't use a Singleton ? I
mean...it is not clear for me when to instantiate a serializer.

Thanks Chris
