Maybe Eliot is able to say something here on the main differences between Cog <-> VW VM.
You made several mistakes: - You didn't post the source code for #tinyBenchmarks. Do all those Smalltalks implement it? Are the implementations equal? - You didn't specify the version numbers for the VMs used. Or if you built them yourself, then the sourcecode + compiler version + configuration parameters. Without these your measurements can't be reproduced. - There are two different Cog VMs. You didn't specify which one did you use with Pharo. - You used a CogVM (JIT) with Pharo but SqueakVM (interpreter) with Squeak 4.2. What's even worse is that you based your conclusion on this mistake. - Does #tinyBenchmarks alone give fair performance comparison? Hardly. Levente
