Last year I contributed a performance optimization to #OpenJDK that makes I/O operations much faster. Strange but true, with existing code often it did not chime in. The reason is that BufferedInputStream was used in many existing applications, which unfortunately skipped my optimization! So I had to fix that class, too! Check out this video to learn what I modified inside of #JDK20 and how it internally works like!
If you missed the original contribution last year, check my channel page, it is covered by a four-parts series!
