SequenceInputStream boosted: Latest OpenJDK Contrib | Java Coding | Head Crashing Informatics 68
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

Small Change with BIG EFFECT | OpenJDK Contrib | Java Coding | Head Crashing Informatics 67
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

BufferedInputStream boosted AGAIN by OpenJDK Contrib | Java Coding | Head Crashing Informatics 65
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
