→Network checksumming
== Network checksumming ==
('''TODO''')
RHEL 5 based kernel supports IP checksum offload.
If network ethernet cards in your host support IP checksum offload then you can switch it features on also for the virtual network devices (venet, veth).
To see current offload settings for the venet0 device, type
# ethtool -k venet0
To set offload settings on for the venet0 device, type
# ethtool -K venet0 tx on sg on
The same applies to veth device.
== Shell scripts performance improvement ==
