Hi Bob

This is great! We already seeing some recommendations on redhat insight for one of our dev systems.

• The performance of InterSystems IRIS server may be impacted when Transparent Huge Pages is enabled
• Recommend running SystemPerformance 24-hour daily for InterSystems IRIS
• Map the Write Image Journaling (WIJ) disk for better performance of InterSystems IRIS
• Enable FreezeOnError for the integrity and recoverability of InterSystems IRIS database
• Apply swappiness recommendation for better performance of InterSystems IRIS
• Apply hugepages recommendation for better performance of InterSystems IRIS
