Hello all, An idea came up recently which I imagine some of you have probably already considered at some point, so I'd love to hear any thoughts you have, or summaries of past discussions you'd be willing to share. Or if this idea is fundamentally infeasible, I'd love to hear that too.
The scenario: we've been investigating a case where many open tabs all embed the same cross-site iframe, and all of those iframes get put into the same process due to the heuristics described in 899838 - Improve process reuse policies - chromium <https://bugs.chromium.org/p/chromium/issues/detail?id=899838>. Ignoring for the moment whether those heuristics are optimal, the result is a single Isolate with many NativeContexts, where each NativeContext loads mostly the same scripts. The idea: could V8 share bytecode and/or Sparkplug code for functions in those scripts? I know that TurboFan code is native context dependent, but as far as I know, both bytecode and Sparkplug code are native context independent. If V8 could avoid generating duplicates, then this scenario would use substantially less memory, plus tabs after the first wouldn't have to wait on tiering up to Sparkplug.
