Thanks Andreas - what confused me is this comment on the Firefox bug tracker: https://bugzilla.mozilla.org/show_bug.cgi?id=1763375#c1 . I took that to mean that Chrome would cache compiled code for regular WebAssembly.instantiate, but I guess that's not the case, and it's only for the streaming functions.
When you say "enough code", what are the current thresholds for caching the module?
