Research direction

Review the existing documentation in the repository to find the appropriate place for node performance troubleshooting. Use the listed causes—load, context switches, GPFS use, and a full /tmp mount—as the required scope, preserving the stated thresholds. Done means these causes are documented clearly for operators, with no file or test path identified in the issue.
