Performance is a combination of speed and accuracy. When the CPU transmits at higher rates, and retransmits
packets fewer times, it has a higher rate of performance. Most users discover performance issues when sending
large files from one CPU to the other.

Although multiple users can send information across the link at the same time, lower shared network resources
can cause slower file transfer time. While data packets are being transferred, available link resources shared by
all users decrease, so when the CPU finishes the job faster, increased shared link resources are made available
for other packet transfers, making file transfer faster.

It is important to query the CPU for performance information occasionally. This allows you to determine when
performance issues arise over time and indicates where you can make changes to improve performance.

One change might require the adjustment of a directional antenna to improve signal strength. Another adjustment
might be filtering unnecessary packets to disallow passage into the wireless link. This type of fine-tuning is
intuitive and one can determine actions, based upon statistics found in the following pages.
