Yes, I really did it! My latest contribution to #OpenJDK 21 will make your #Java program drive I/O bytes up to twice as fast through your streams. If you like this video, please give it a thumbs up, share it, … Continue reading →

If you are using SequenceInputStream, you will notice that it pulls all data into the JVM’s memory, just to drain it to another I/O sink. This is inefficient and slow. With my latest contribution contained in #OpenJDK 20, this will … Continue reading →

Contributions to #OpenJDK don’t have to be huge always. Sometimes it is the small things that have BIG EFFECT. For example if a class was intended to be non-synchronized (hence: fast), implicitly is synchronized by mistake (hence: slow), is finally … Continue reading →

As #PushbackInputStream is quite similar to #BufferedInputStream, it was rather easy for me to apply the performance optimizations I already developed for BufferedInputStream to the PushbackInputStream. The contribution was accepted in November 2022, so it is now part of #OpenJDK … Continue reading →

Recently I boosted #BufferedInputStream by contributing to #OpenJDK. There was one case open, in which performance did not excel. Now in my new contribution to OpenJDK, which is contained in #Java 20, I fixed this – so in two thirds … Continue reading →
