hello, Test seems old, both virtual machines (VW and Pharo) have upgraded in the meantime. VW has always been faster that Pharo for what I know, up to recent time. Recently Pharo changed the vm technology so now it should be much faster, but I don'r know is faster that VW , so it would be nice to have a up to date comparison. Related to Matrix, this is a nice way to have many smalltalk images running in parallel, but it doesn't seems the case of this test. It requires a specific way of writing the code, it is not as automatic as defining a piece of code "parallel". The thread model of VW and Pharo are still the same, green thread and (almost) single core systems
