Such an excellent and clear talk. I met Jack in a conference and he is a very down to earth and approachable person. Look forward to more such talks from him.

one of the great talk I've watched, I am gonna watch it again and I will take some notes to further searches.

Unbelievably clear talk. Thank you, Jack.

I love this guy as he really wants to share his knowledge and help people with these sorts of issues. I hope we can find his complete talk elsewhere.

Great video, thank you!

wow this is gold, thank you

Great talk!

searching for some talk like this for years.. finally found one!

was very informative, makes you want more.. I just wanted to watch 5 minutes of this video, but ended up watching up to 42 minutes without realizing when he starts saying he only has time for two more slides, I was like is 45 min up already? Grateful for such minds.

the amount of useful information per second -> infinity

Brilliant!

Great talk. Learned a lot. Having knowledge on how the jvm works as well as database internals would nice a nice links as well.

Good explanation...

awesome presentation............................thanks Jack Shirazi.......................:) ...........................bye

Great talk! Wonder is this presentation slides downloadable ? Thanks

I want to double thumbs up! What a nice guy! I think I know him from WWF Rage ;)

This is gold

Where can the presentation for this video be found? The speaker mentioned several times it's all in the presentation.

thanks, excellent talk, curious about how visualvm sampler can help

Did anyone find the JLobby report for Java Persistent options that Jack mentions @13.42 ??

Terrific presentation...superb explanations of basic & complex stuff. TY Jack ! One thing I didnt get was why the ref. to RMI...isnt it defunct ? And why on earth 10,000 in the title ??

Amazing. Unless "amazing" means "feeling overwhelmed as though lost in a maze." In which case this is the opposite of that. Unmazing.

Where can i download slides?

where can we get the slides for this ?

can anybody help if there are notes on Java Performance the definitive guide

whats the reason for not using jvisualvm in production? performance overhead? data corruption?

Their license forbidding to use it in production for free. Although VisualVM is bundled with a JDK, you can use it for free only in development environment.

The most important reason is Visual VM is a sampling profiler with a "safepoint bias". What it reports as the "hot method" (which is _the_ purpose of a profiler) may be completely misleading and you may end up wondering what method in your code is actually slow.

I'm from the future, Java now has ZGC which achieves sub millisecond pause 🥳

Is this slideshow available, you skipped over the part I cared about?

2:24 They put millions what into it?

He is referring to engineering time

I did not get What does He means by "outliers" and "inliers"?

@kedarmhaswade

I think it just means the outliers are not likely to appear in your (and my) app. We are just writing typical apps and they are the inliers (a term that he means to be opposite of outlier). For us typical app developers, he discusses the things to focus on.

Outliers are things which are hampering the performance of the application which are introduced by the outside happenings around the application which is not controlled by the application.

I guess you need a bit of experience in garbage collection modification and all these tools and diagrams before you should watch this.

Brilliant !!!
