Abstract: Some installations implementing parallel sysplex have seen performance issues due to XCF signaling. These performance issues are generally solved by tuning changes to the XCF transport class definitions, buffer definitions, and signaling paths. This document is intended to review recommended XCF configurations and known performance tuning options.

This white paper is a complete replacement for WSC FLASH 10011 XCF Performance Considerations.
