Restrict process and Buffer globals to CommonJS by guybedford · Pull Request #26334 · nodejs/node (original) (raw)
I'm going to be spending some time profiling what is going on. I don't see code related to this in inspector profiles or --prof that would make the time difference make sense. I'm wondering if something odd is happening and will have to dig into opts/deopts a bit. The only other alternative for what is causing stuff is the context wrapper but I would have to talk to V8 about why it isn't being optimized away which might take time.
