are you going to measure the change in a newly built VM, or in the interpreter simulator,or...? If you look on the VM list (and this list I think) there are a number of benchmarks used for comparison. #tinyBenchmarks is one. cheers, Mike 2010/4/2 Mariano Martinez Peck <marianopeck(a)gmail.com>: > Hi folks.

[Pharo-project] How to measure VM changes from the image side

by Mariano Martinez Peck

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

What you mean by obfuscating the point what i missing? I never said that classes doesn't require special handling.

Sig, SIXX will do what you describe, but I respectfully submit that you are missing the point - worse, you appear to be going out of your way to obfuscate it: there are indeed objects (classes are among them) that require specialized serialization.

Monticello provides various serialization methods for classes: a binary one based on reference streams, and one based on the file-out mechanism. Monticello 2 uses a custom (binary) serializer for classes. Lukas -- Lukas Renggli www.lukas-renggli.ch

There's also a #defaultMethodTrailer in Behavior defaultMethodTrailer ^ CompiledMethodTrailer empty so, you could use it instead (to leave chance to change it in future to something else, and avoid direct reference to CompiledMethodTrailer in many places). > Stef > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Best regards, Igor Stasenko AKA sig.
