Adapter Settings
The following adapter settings can be adjusted for better performance.
Use taskset to tune CPU affinity on Opteron systems with the QLE7240, QLE7280, and QLE7140. Latency will be slightly lower for the Opteron socket that is closest to the PCI Express bridge. On some chipsets, bandwidth may be higher on this socket. See the QLogic HCA and InfiniPath Software User Guide for more information on using taskset. Also see the taskset(1) man page.
Use an IB MTU of 4096 bytes instead of 2048 bytes, if available, with the QLE7240, QLE7280, and QLE7140. 4K MTU is enabled in the InfiniPath driver by default. A switch that supports and is configured for 4KB MTU is also required to use this setting. To change this setting, see “Other Configuration: Changing the MTU Size” on page
