   Pretty cool talk segment from the GraalVM lead dev where he makes a "ahead of time compilation > just in time compilation" case.
   
   He compares several metrics to come up to this conclusion, such as peak throughput, throughput/memory ratio and overall memory usage. He later explains why JIT supposed gains (constant tuning) do not always pay off in practice.
   
   That's pretty much in opposition to what I heard for the last 10 years. His case his built on a single, likely not representative of all loads, example. But the guy has been working on a JIT java VM for the last 15 years, I guess he knows what he's saying to some extent.
   
   I'm by no means an expert in JITs, I can't determine whether this case makes sense or not yet.

     @Profpatsch This is precisely the assumption I've been hearing for the last 10 years that's "debunked" in the talk.

     @Ninjatrappeur JIT on a good VM can give you superior management in production though, adjusting things and monitoring without a redeploy.

     @Ninjatrappeur I think "I can do it live" is a slightly different nuance from "it can do it live", but I admit I didn't watch yet, maybe the talk addresses both?
