<p><b>New page</b></p><div>TSO support for 'venet' and 'veth' has been added to RHEL5 kernel 028stab064.4.<br />
<br />
This feature increases bandwidth or considerably decreases the CPU usage if the physical Ethernet adapter supports TSO.<br />
<br />
== TSO management details ==<br />
# TSO is off by default.<br />
# For veth: TSO can be enabled/disabled in containers or on the HN for a pair of adapters (veth in a container, veth on the HN).<br />
# For venet: TSO can be enabled/disabled only on the Hardware Node (for all venet devices at once).<br />
<br />
To use this feature, you must enable:<br />
<br />
* TX checksumming: <code>ethtool -K DEVNAME tx on</code><br />
* Scatter-gather: <code>ethtool -K DEVNAME sg on</code><br />
* TSO: <code>ethtool -K DEVNAME tso on</code><br />
