Laurent, I will preface this by saying that I have had a fairly intense week with Pharo. I am closing in on a solution to a real problem. I greatly miss Dolphin's Browse-it command, and its F12 and shift-F12 (definitions/references to a typed selector); the message search has its points, but it takes some extra steps to use in comparison to the Dolphin features. Back to the topic at hand; let's see if I am following. Start with a core image, run a script that installs what looks like a Pharo web image, makes a few changes to settings in favor of speed, and you get something that you find faster than Pharo?? Did you make the same speed selections in Pharo? If so, one wonders what happened between core and Pharo-dev/web that Lukas did not do to the core image. Sorry if I'm off base here - it's been a long and very good few days.
