This dictionary is never reset. properties and queries : those two are caches that can be reset. They save the result of long operations as #numberOfLinesOfCodes But I do not know why we have two dictionaries instead of one and I would like to know. This is what my Window's memory manager tell me. I'm sure we can remove a lot of thing but I was waiting more progresses on the Bootstrap to explore the possibility to reduce image size. After loading a model we launch the build of some caches in order to get usable interfaces directly. Else some browsers can take 30sec to first load then they take less than 1sec. To avoid this we generate some of those caches at loading. The most interesting part is when we already use caches. The grow in memory of the caches is reduced. I tried in the application I am working on and there is none in this model. Here is the script: states := MooseModel allSubInstances first entities collect: #privateState. MooseDefaultState compile: 'allPropertiesKeys ^ propertyCache keys'. MooseDefaultState compile: 'allQueriesKeys ^ queryCache keys'. properties := states flatCollectAsSet: #allPropertiesKeys. queries := states flatCollectAsSet: #allQueriesKeys. properties size = (properties \ queries) size.
