Network performance

AIX provides several different communications protocols, as well as tools and methods to monitor and tune them.

TCP and UDP performance tuning
The optimal settings of the tunable communications parameters vary with the type of LAN, as well as with the communications-I/O characteristics of the predominant system and application programs. This section describes the global principles of communications tuning for AIX.
Tuning mbuf pool performance
The network subsystem uses a memory management facility that revolves around a data structure called an mbuf.
ARP cache tuning
The Address Resolution Protocol (ARP) is used to map 32-bit IPv4 addresses into a 48-bit host adapter address required by the data link protocol.
Name resolution tuning
TCP/IP attempts to obtain an Internet Protocol (IP) address from a host name in a process known as name resolution.
Network performance analysis
When performance problems arise, your system might be totally innocent, while the real culprit is buildings away.
