Thanks a lot for making talks like this one! Java low latency is a pretty narrow topic, and it is not easy to find information about. Videos like this are worth a lot to us performance afficionados :-)

[@SHates]

Fascinating talk! Really enjoyed learning what goes into creating these sorts of systems.

[@tamerator]

Great session! Well done.

[@joepage3065]

Thanks Daniel, really good presentation.

[@jonofsasek2820]

Excellent introduction to the topic for a seasoned Java dev interested in this matter :) Thank you Daniel

[@nitindandriyal]

Good One, Thanks!

[@AntonioDoesMetal]

Just dropping in to say this is an amazing talk, it's usually pretty hard to listen to talks like these from beginning to end but this one was very captivating

[@MuztabaHasanat]

Great talk.

[@tarasmurzenkov148]

Amazing talk.

[@TheYogai]

Excellent example with a bike! I'm going to use it. :) I was already of opinion that latency needs to be considered even before we build, that is, during the design and your bike example is perfect illustration of this.

[@vahidsadeghi5491]

Really great talk, I've got lots of ideas

[@mjwchapman]

One of my all time favourite presentations. I often come back to this one and another by Mark Price. And now that records are finally a thing I wonder if the Java version of Aeron has managed to catch up with C#...

[@lecardinal1]

really interesting tips to follow to reduce latency of a system based on microservices. Thanks

[@world_affair]

great talk

[@piotrborowczynski8082]

Anybody knows the name of the podcast he mentions at 27:55?
BTW, this is a very interesting talk, thanks!

[@nathanieldoromal6904]

The language comparisons at time 14:45 don't show the true power of C++. The top-tier finance firms were doing

[@KiyoshiDaichi]

Low Latency ?!, Yes Please !!

[@programmingeverything]

Jump to 27:38 for tldr

[@VictorZamanian]

And even then, at 28:00 ish, he's like "again, let's digress"...

[@LaurentLaborde]

Good speech, but by someone who doesn't know modern C++ (i use java & kotlin more than C++, but when i do, i never need to deal with pointer. RAII and auto& are magic)

[@xv179]

17:09 this person clearly has never used C++ and if it has used C++ probably used the '98 standard... My friend, C++ has evolved a lot, you need to brush up your C++ a little bit. The justifications presented in this talk only justifies using Java over C++ because of time-consuming which is not necessarily true. Anyone who masters C++ can write faster or equal than any Java developer... "time to develop" it's a pretty mediocre justification for using Java over C++

[@michaelmorris2300]

What is the JVM written in? C/C++? If so, then what is Java really?

[@yangyun6221]

smart pointer made c++ a modern language

[@muhdiversity7409]

@@michaelmorris2300 Pie in the sky that have adherents gaslight you over and over again that their bouncy castle is best. Trust me, bro.

[@judgegroovyman]

The presenter completely addressed this at 21:00
