Hi folks. I am playing with some important parts of the VM and I would like to measure the impact of this changes. As an example, I am changing the Interpreter >> normalSend which is the code that represents the send of a message (at least that's what I understood). So, you can imagine that this will have an impact ;) So...what I would like to know if is someone has ideas of how can I measure this impact. I though some benchmarks that can be run before and after this change. In Java I know that there are some libraries or suites of benchmarks already written for this kind of purpose or similar. Is there something in Smalltalk ? Do you have some ideas for this ? It would be cool not do depend on network traffic or things like that. It would be cool also if I can do it directly from code so that it is repeatable. Maybe something that requires a lot of process, time, and involve a lot of objects...ideas? I though running all Pharo tests, or test coverage, ScriptLoader cleanUpForRelease, or cleanUpForProduction, run Lints Thanks in advance. Mariano
