If you’re interested in how we use Java at Netflix, Paul Bakker’s talk How Netflix Really Uses Java , is a great place to start. Operational simplicity Service owners often reach out to us with questions about excessive pause times and for help with tuning. No explicit tuning has been required to achieve these results.

There's no Java stack—there should be a tower of green Java methods—instead there's only a single green frame or two. This is how Java flame graphs looked at the time. Later that year I prototyped the c2 frame pointer fix that became -XX:+PreserveFramePointer, which fixes Java stacks in these profiles.
