A few more small optimizations

Day 4 /  / Track 1  /  RU / Introduction to technology

In new versions of Java, there are not only many new cool features and global performance improvements like new garbage collectors. There are also many new small improvements in the standard library that few people know about because they rarely make it to articles and blog posts. Tagir released the first batch of such optimizations at the Joker conference last year. According to the feedback the audience enjoyed the dish, so let's repeat it. We will look at some optimizations that were not included in the first talk included those that will appear in Java 15 and discuss how and why they were made.
