3.5.2  Performance tuning options
These steps illustrate what you should do to solve problems related to network bottlenecks:
򐂰
Ensure that the network card configuration matches router and switch configurations (for 
example, frame size).
򐂰
Modify how your subnets are organized.
򐂰
Use faster network cards.
򐂰
Tune the appropriate IPV4 TCP kernel parameters. (See Chapter 4, “Tuning the operating 
system” on page 91.
) Some security-related parameters can also improve performance, 
as described in that chapter. 
򐂰
If possible, change network cards and recheck performance.
򐂰
Add network cards and bind them together to form an adapter team, if possible.
