The following parameters affect adapter FCoE performance:
Operation Mode
Interrupt Delay Timer
Execution Throttle
Frame Size (Fibre Channel)
The Execution Throttle and Frame Size Rate parameters default to their maximum values for optimal FCoE performance. The following subsections describe how to use the Operation Mode and Interrupt Delay Timer parameters to improve adapter FCoE performance.
Operation Mode (ZIO)
The Operation Mode (ZIO) parameter specifies the reduced interrupt operation modes. ZIO modes allow the posting of multiple command completions in a single interrupt. Table
