And Pharo 1.4 running in a StackVM has been replaced by Pharo 2.0 running in a CogVM. That is worth some serious performance points as well, indeed. BTW, I see that you have enabled gzip compression server side as well, using Zinc ? That means you are using a very recent version of Zn, which one ? Anyway, more performance improvements are underway. Sven

Additional not-used code cannot have a benefit but it could cause side effects (breaking things, slowing things down, opening security holes, etcâ¦). So you reduce it to the bare essentials. Having less code also makes an image faster which is not a noticable effect but it is there.
