At any rate, I’ll file an issue tomorrow and share what I can. Thanks for the nudge to do so!

FYI we actually set space_overhead as low as 15 in production. It seemed a bit excessive to me but that’s what was necessary to match the characteristics of OCaml 4 in practice.

Unfortunately I don’t think I’ll be able to make a publicly available repro case for this. I may be able to get source code access for a limited group, and I can definitely try out changes to the runtime and report back. Let me know if either of those two options sound good to you.

I’ll do what I can to get you the information and access you need if you’d like to look into this. The bulk of the work here was needed for our proprietary interfile analysis. I did need to change space_overhead in the community edition too, but a static value sufficed to match OCaml 4’s performance
