Dive into the latest advancements in #Java with our latest article on JDK 21's virtual threads: https://bit.ly/4cEppIA

This analysis compares the performance of virtual threads with Open Liberty's thread pool, focusing on key findings such as throughput, ramp-up times, and memory footprint. While virtual threads offer several advantages, they also show unexpected performance issues, especially in CPU-intensive workloads.

This analysis guides Java developers on when and how to use virtual threads in their applications.

12 Lessons Learned From Doing The One Billion Row Challenge:

#java #1BRC #jvm #jdk21

There has been some interesting discussion on #JakartaEE 11 and #Java servers over on Twitter. The draft of the spec has been updated to require JDK 17 rather than requiring JDK 21. I agree with the decision. To maximize adoption, JakartaEE must support JDK 17 and optionally JDK 21. Dropping JDK 11 is the best we can hope for right now.

My CalculateAverage code has been executed for the #1brc challenge.
I didn't get the expected result on the advertised "This CPU will impress you with its multi-tasking performance." CPU (See graph).
Also did some jdk8 tests.

Time to refactor the code...

I've created an open-source Java library to make code using virtual-threads easier to write and to read.
Check it out on GitHub: https://github.com/japplis/Virtually

It's already in Maven repository.
