The Speculation Rules API is designed to improve performance for future navigations. It targets document URLs rather than specific resource files, and so makes sense for multi-page applications (MPAs) rather than single-page applications (SPAs). The Speculation Rules AP

Fast as C: How to Write Really Terrible Java
For years we’ve been told that the JVM’s amazing optimizers can take your running code and make it “fast†or “as fast as C++†or “as fast as Câ€â€¦or sometimes “faster than Câ€. And yet we don’t often see this happen in practice, due in large part to (good and bad) development patterns that have taken hold in the Java world. In this talk, we’ll explore the main reasons why Java code rarely runs as fas
