This is importing additional information given in the Opster docs for high cpu issues.

Summary of changes:

  1. Moved the “Hotspotting” paragraph at the beginning into the “Tips and Solutions” section for better contextual fit, incorporating extra details from the Opster documentation.
  2. Added new subsections to “Tips and Solutions,” specifically covering JVM garbage collection and oversharding.
  3. Separated the previous three points (“Scale your cluster,” “Spread out bulk requests,” and “Cancel long-running searches”) into a distinct section, as they are less common scenarios and more general best practices rather than direct solutions to typical high CPU issues.
