Java and OpenJDK are trademarks or registered trademarks of Oracle and/or its affiliates. The Stream API makes it possible to execute a sequential stream in parallel without rewriting the code. ZGC does such a good job keeping the pauses short that we start to see other things affecting the latency score. C# vs Java performance is a topic of a heated debate among programmers. Java 17 was released on September 15, 2021. It is based on the OpenJDK but includes a new high-performance compiler and a new polyglot virtual machine (can execute code written in different programming languages). It is, however, unclear how significant these changes are; the description would suggest that only the scope of JEP 310 was added. allows monitoring and profiling of a running Java application at a low (target 1%) performance cost. Switch is present in a lot of languages, but over the years it got less and less useful because of the limitations it had.

Has Microsoft lowered its Windows 11 eligibility criteria? Java 8 brought a big change to the Java language. A plausible explanation is that it is no longer reachable and has been garbage collected by the time that VisualVM has created the heap snapshot to examine. Since both Parallel and ZGC have been pretty stable from this perspective, it makes more sense to look at raw numbers here as well. Java 18, on the other hand, will only be a smaller update with some additional features, and 6-months-long support. Its a paid subscription which you can buy to get some Java 17 features such as the G1 garbage collector in Java 8.
