<?xml version="1.0" encoding="UTF-8"?>

<!--
  A trimmed down version of the default JFR profile configuration. The primary goal is that it has enough execution samples so that
  we can diagnose common performance issues in IntelliJ. Only events that don't significantly increase the space of the recording are
  included. The configuration is of sufficiently low overhead that it can be just left enabled if desired. The original version
  was documented as having less than 2% overhead, and we've removed many events from it, so this is likely to introduce 1% overhead or less.

  The list of available events is documented at src/hotspot/share/jfr/metadata/metadata.xml.
