Understanding Java Garbage Collection

Gil Tene, CTO, Azul
Garbage collection is an integral part of application behavior on Java platforms, yet it is often misunderstood. Developers have choices in selecting and tuning collector mechanisms as well as in application architecture. This session reviews and classifies various garbage collection techniques available in JVMs today. After a quick overview of common garbage collection techniques such as generational, parallel, stop-the-world, incremental, and concurrent algorithms, it defines terms and metrics common to all collectors. The presentation also classifies each major JVM collector’s mechanisms and discusses the trade-offs involved in balancing requirements for responsiveness, throughput, space, and available memory.

Such a wonderful talk. I just wish there was a way to get rid of that awful knocking sound.

[@beatagozdziaszek8157]

I was thinking the same .

[@zombi1034]

Should be doable using some kind of AI model. Maybe KZbin will add something like this eventually😂

[@MarkusJevring]

Man, the sound here is awful. I really hope the other sessions are better. KZbin needs some kind of equalizer to tune that kind of shit out, if possible.

[@coolmanjack1995]

This actually sounds like a really bad compressor job or a poorly set noise gate. Some cheap microphones have built in compression that sounds really shitty like this but this has to be some kind of compressor built into their audio board or something that just isn't cutting it. Notice how when he stops talking the static gets louder because the compressor is normalizing the white noise with the volume of his voice. Also his voice keeps cutting out so whatever it is that makes the compressor work has a poorly setup trigger where it responds late and sometimes on the wrong part of the audio. It's like a really shitty autotune job where a long sustained note starts bouncing back and forth because the singer is singing in a note they dont have the program keyed for. This thing just isnt listening for the right sounds and seems to sometimes mistake his voice for noise or the noise for relevant audio. 0/10 wouldnt recommend this setup

I will spend more time to understand what you talked in this show Thank you

[@igrai]

Very informative But the sound is horrible

[@freindimania11]

Horrible audio, there's the same talk by him in Azul channel. If you also struggle like be - this will help

[@dmytrooleinichenko9865]

This noise sound is annoying

[@DomKeon]

Interesting watch, thanks.

[@priyodas755]

Nice session ruined by this disgusting noise

[@vishalakkalkote1344]

One of the good talks I heard about GC. only disappointment as that awful knocking sound coming intermittently.

[@alexeibrinza2719]

Great talk, however background sound is really annoying.

[@garvisrobot9274]

Good talk but the worst way to record talk.

[@alexfray7297]

Really good presentation but that lack time for speaker in the end is not good

[@FishL0L]

He skipped the most interesting part. It gets me upset

[@neuronist]

whats that?

[@_Anna_Nass_]

do tell

[@paulfunigga]

What is that sound of something bouncing off the table? Why not remove that noise before uploading the video?

[@vaibkv]

Knocking sound as well as continuous white noise.

[@kcheban]

Perfect content. Thanks

[@gregbugaj]

Great technical info

[@ga7073]

So good, thanks!
