With this window you set some of the parameters used by the capture engine.
Capture buffer size: it sets the size of the capture buffer in the packet capture driver; buffer size is the parameter that influences the number of packets loss during a capture; on the same machine a bigger buffer means lower loss probability. Anyway Analyzer prints a message box when detect losses, therefore we suggest to increase this value only when it is strictly needed.
Number of packets...: capture can either proceed unlimited or can end when the selected number of packets are received.
Set capture in promiscuous mode: make the capture driver able to capture all the traffic transmitted on the network, otherwise only traffic from or to that station can be captured.
Section of the packet...: it sets the parameters which define the number of bytes copied by the system in the packets buffer. The packet capture driver copies only the selected amount of bytes to the buffer and not the whole packet; in this way the processing time, absorbed by the copy task, diminishes. So this parameter is one of the most important when talking about performances.
These parameters are saved in the Analyzer.ini file.
