Yesterday Async-profiler 4.0 was released. One of the new feature is "native memory profiling". One of the use case is finding native memory leaks. More on that topic in my new article: krzysztofslusarski.github.io/2025/03/31/nat…
Any tips where I can get cheap Multi-CPU NUMA metal instance for few hours?

Async-profiler is also great, especially with krzysztofslusarski.github.io/2022/12/12/asy… as a resource (@k_slusar)
Profiling virtual threads with async-profiler vs. JFR. I wish developers used proper tools more often.
Ever wondered what keeps profilers awake at night? Its thoughts on jmethodIds: Let me show you why and how I intend to remedy the situation in my new blog post mostlynerdless.de/blog/2023/07/1…
@k_slusar on the stage of @confiturapl :D Yes, there is music as well! 😁
We're excited for Saturday because of the upcoming speaker, Krzysztof Ślusarski. He's well-versed in Java with extensive experience as a trainer and speaker - you can meet him very often at @WarszawaJUG meetups 2023.confitura.pl/speakers/3c188…

Couldn’t we just use AsyncGetCallTrace in a separate thread like JFR does? We can... If we slightly modify the API :) I discuss the different approaches, advantages, and disadvantages in my newest blog post mostlynerdless.de/blog/2023/04/2…
Finally !!!!! The issue that I was describing here: krzysztofslusarski.github.io/2022/03/21/eve… is fixed and backported to JDK 17 and 11.
