Hi Yang, Yes, ideally this functionality must be built into Chromium (or V8 depending on the right place). And that was my initial question too... Is it possible to configure it? If it is, then at this time I am only interested in evaluating it on such systems where I suspect bytecode caching in service worker is problematic.
Looks like the answer is *no such option is available *today.
