Hi Holger,
With Pharo3 I was proceeding like this, by uninstallation of packages. However there is the promise of building from a minimal image, but it is not documented AFAIK.
By curiosity, what is the size of your resulting image.
I see 31mb image size for Pharo3 and 49mb for Pharo6. The changes file is about the same. From the top command on a test system. "pharo" is a Pharo6 VM and image and pharo-vm is the pharo3 system. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4206 root 20 0 1056684 74036 1600 S 5.7 1.2 1582:15 pharo-vm 10459 root 20 0 104040 90348 2124 S 5.0 1.5 369:00.29 pharo I looked a bit at memory usage and see if some random changes make a difference * Shrink ZnMimeType ExtensionMaps to a minimum when not handling extensions? * ASTCache reset to get rid of the spotter cache. Not sure if the SessionManager runs ASTCache>>#shutDown properly. It looks like it should but it doesn't? * ByteString compaction? I did strs := ByteString allInstances. str -> strs asSet. The numbers on a not fully clean image are 99874 vs. 42139. I wonder in which hell I end if I use >>#becomeForward: to compact it (I tried this once for GNU Smalltalk and I am sure others tried it before). I think anyone using == on String is using the wrong class? Any good arguments against doing it? I am moving my Pharo6 image into production right now and then will look into setting up CI for Pharo7 with a minimal image. cheers holger
