New Blog Post 🚀 "JVM Performance Comparison for JDK 21" A deep dive into JVM performance comparison where @gigiblender and I explore different optimizations in OpenJDK C2, Oracle GraalVM, and Graal CE JITs ionutbalosin.com/2024/02/jvm-pe… #OpenJDK #GraalVM #JDK #Java #performance


If you're in Vienna on November 28th, join me at the "Java and Friends Meet-up," where I'll be speaking about "Application Security for API Microservices: Key Principles and Flows." . 🍕 Pizza and engaging conversations are guaranteed! 🔗 Link: meetu.ps/e/NCDhh/txxrK/i


🚀 I just made my Java Application Security Practices repo public. It contains some OAuth 2.0 flows, API security, deserialisation attacks, SAST/DAST/SCA integration, and more. A must-have for every #Java dev focused on security. 🔐 Check it out! 👉 github.com/ionutbalosin/j…

Why JVM modern profilers are still safepoint biased? by Jean-Philippe Bempel jpbempel.github.io/2022/06/22/deb… @jpbempel #jvmperformance


Had a great time at #Java #Vienna meet-up with @venkat_s tonight! It was very nice meeting and talking to you, as always.

For running serverless apps, it can be quite important. Also for command line apps. For a detailed discussion how the @GraalVM JIT mode shows better peak performance, see this blog post from @ionutbalosin for example: ionutbalosin.com/2024/02/jvm-pe…

@PeterVeentjer's latest blog post about how HT actually works (free Boxing lesson for the 1st person to post an indepth writeup on "Rentable Units", Intel's rumored HT replacement). Low-latency peeps? Just say "NO!" to HT: pveentjer.blogspot.com/2024/04/how-do…
