[VM] Method Lookup

Hello,

For the Classbox Model I have implemented a new method lookup. I have a strange result I could not explain. The new algorithm is 25% slower (according some personnal benchmarks for testing monomorphic and polymorphic messages). But the whole environment is 5 times slower (benchmarks for opening and closing Scamper, Celeste)...

Anyone has any idea why with a lookup mechanism 25% slower I get an environment 500% slower ?
It seems to be related to the cache mechanism...

Cheers,
Alexandre
