Please note that the post didn't mention the word benchmark a single time ;) It does a "basic performance measurement" of "our csmith example". Anyway, thanks for your notes, they …

RuntimeDYLD is legacy, you might want to switch Postgres to use JITLink instead: https://llvm.org/docs/JITLink.html

Scam?

Interesting, because we store relocatable objects. And process symbols can be resolved by name if you really want. It might be yet another performance trade-off though.

> There is one way to make the LLVM JIT compiler more usable, but I fear it’s going to take years to be implemented: being able to cache and reuse compiled queries. Actually, it's …

That really works great for people who have 100M times more lookups than inserts/deletions and less than 3K nodes :)

Great in-detail article, thanks! In the last paragraph you state that pseudo read-write-ex­ecute maps work "on the shiny new Apple sys­tems". Do you mean M1 with macOS 12 on arm64?…

They moved to LLVM 12 and OrcV2 https://github.com/postgres/postgres/commit/6c57f2ed16e12810...

No big surprise given the past riots against multinational companies in the district [1]. Apparently those responsible knew about that as much as they care about people & culture h…

The problem with +2° is, that we will be at +5° soon after. Phase III is an irreversible chain reaction.
