Jumbo Frame (MTU 9000) ใน linux ทำเพื่ออะไร

Jumbo Frame (MTU 9000)
The RPN network support Jumbo Frames, this means you can configure your network adapter with MTU 9000.
The performance gain can reach up to 20% on resource-intensive applications such as iSCSI, NFS, and DRDB.
To know your current MTU you need to type:

#ifconfig eth2 | grep MTU



Modification of the MTU to 9000
Linux
=== Debian / Ubuntu ===
In the file /etc/network/interfaces you need to add

  auto eth2
  iface eth2 inet dhcp
  mtu 9000
and type

#ifup eth2 
or

#/etc/init.d/networking restart
=== Centos ===
In the file /etc/sysconfig/network-scripts/ifcfg-ethX you need to add (X = the number of the interface)

  MTU="9000"
and restart the network

#service network restart
