There was a great tech talk I watched by a guy with an Irish accent (definitely non-american european) discussing cases were jvm apps outperformed managed memory apps thanks to runtime compiler optimizations, in the context of trading and/or financial services. Does anyone have an idea of the developer or talk I am looking for? Trying to find a link to the talk for a colleague.

Maybe https://www.infoq.com/presentations/jvm-dynamic-optimizations/ ?

could maybe sort of be an Irish accent if you squint ¯\_(ツ)_/¯

nope not that one, but somehow your response motivated me to think harder and I realized I hadn't checked my browser history. I found it!

i like this presentation. this landscape changes so quickly it's hard to take even a 2017 video seriously.

https://github.com/jnorthrup/PrematureXorSwap i recently wrote a micro benchmark for java. cheers!

@jimn nice benchmark! I suggest polish them by using JMH. it's a very powerful framework for such micro-benchmark, developed and motivated by Aleksey Shipilёv, who is the author of an outstanding JVM performance-themed series articles https://shipilev.net/jvm/anatomy-quarks/

@Ray Eldath I'm not opposed. I'm sort of hoping to run across someone who is OCD for benchmarks and can add the perfect boilerplate along with the test itself to a bigger study.

[Ray Eldath]

well, anyway, it's still an interesting benchmark 😉

@Ray Eldath thanks for the blog link that's really great stuff!
