Hi devs, I've done some memory analysis with yourkit and it happens that the EM takes a lot of memory, namely: * DefaultCoreExtensionRepository takes 31MB of memory as it caches all extensions found in memory * Out of the 31MB, 29MB is used by org.apache.maven.model.Model with 373 instances (I guess that's the number of extensions we have) * Note that 15MB is taken just by Xpp3Dom objects (42814) for the goals of the plugins of the extensions * 10MB by PluginManagement The question is: are we ok with this? Should we reduce it? On a different note, PyDictionary takes 11MB of memory. Actually the total memory taken by python is much more, I've computed to be 50MB, that's quite a lot just for our code macro… Thanks -Vincent
