Enhance network bandwidth

On K2 Summit system with K2 system software, the on-board network adapters have a performance limitation that causes them to function at half the expected bandwidth. On most systems, there are no symptoms related to this limitation, as network traffic is below the limitation. Systems using ShareFlex or having other requirements for high network bandwidth might be impacted to some degree. Symptoms include general network bandwidth restrictions, slow iSCSI or LAN Connect I/O performance, slower than expected FTP traffic, and other slowness not caused by other factors.

Grass Valley requires that you remove the limitation and enhance the network performance. Once the limitation is removed, the change persists throughout normal software upgrades. However, if you reimage the K2 Summit system system you must check and reapply the change if necessary.

To remove the limitation, disable "Large Send Offloads" on the network adapters and disable "CPU Power Technology" in the BIOS.
