HP-UX 11i Tuning and Performance

10.9. Tuning Network Bottlenecks

The three ways of tuning network bottlenecks include hardware solutions, configuration solutions, and application solutions.

10.9.1. Hardware Solutions

There are a variety of hardware solutions, all of which can be thought of as “spending money” solutions. Here are a few common approaches:

• Add more network adapters and rebalance the network load, say with Autoport Aggregation.

• Use faster network adapters (e.g., Gigabit Ethernet versus Fast Ethernet).

• Use switches instead of hubs.

• Use higher-performing switches.

• Use network adapters with checksum offloading to perform the checksum operation in hardware versus software.

• Use Auto Port Aggregation (APA) software to load balance multiple NICs onto a single logical network. ...
