Leszek,
Thank you for turning me on to the possibility of using an interceptor of a
predefined object. This may be the gateway to several other approaches for
integrating parallelism to V8 that sidelined me. I'll admit the last time
I wrote code using V8 headers was v0.9 and now my full-time

All,
Since this topic has already prompted so much work and discussion I'll
chime in as an opinionated but passive community member whose project is
also ultimately limited by being able to reason about the storage sequence
of V8 objects.
Startup time is often a driving consideration, but any
Hi Leszek,
Apologies for the delayed reply - I've been a bit swamped at work the past
couple of days. Thank you for the excellent details & we'll align our plans
accordingly. Some replies inline.
I've replied privately to Jacob's concern as I don't want to derail this
conversation.

In addition to the excellent technical points that Leszek explained, I just
wanted to clarify additionally that we don't have a concept of "major
releases 8 -> 9" etc. V8's version numbers are assigned by adding 0.1 every
six weeks, rolling from x.9 to (x+1).0. There are *zero* technical or

Hi Vitali,
Stabilising the cached data format as-is is pretty challenging; the cache
as written is pretty much a direct field-by-field serialisation of the
internal data structures, so freezing the cache would mean freezing the
shapes of those internal objects, effectively making the internal f
Hi Vitali,
I’m neither from the v8 team, nor an expert in this subject matter. Just
wanted to drop an interesting project: Hermes - https://hermesengine.dev ,
a javascript engine by Facebook that is tailored for fast startup times. It
does this by precompiling javascript into bytecode at build tim
Hi,
I wanted to kick off a discussion and solicit some thoughts on whether it
would be operationally feasible to try to stabilize the cached data format
of the compiler.
The context is that I work on Cloudflare Workers. We'd like to increase the
script size we allow our customers to upload, but w
