I should clarify: that's the memory consumption that's identified as belonging to the compartment, but that's not the whole picture. Some compartment data gets reported at the level of the runtime, including 'script-sources' and 'script-data'. Our increase for these over the past year is 1.5 MiB (see https://bugzilla.mozilla.org/show_bug.cgi?id=986323#c1). That's purely due to loading more code, and is unrelated to compartment overhead. Lazy loading will help there. Nick _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
