When you change the buffer size, you may experience a delay as
Sniffer Portable Professional allocates the memory for the buffer,
especially if you specify a large buffer. Keep the buffer size less
than the size of the capture buffer plus 10MB.
Figure 6-2. Setting Capture Buffer Options
Setting Large Capture Buffer Sizes
This release supports capture buffer sizes from 256K up to a maximum
of 384 MB). You must have at least 10MB more memory than the
specified capture buffer size for capture to start. For example, to
start a capture with the buffer size specified as 64 MB, you must have
at least 74 MB of memory in the system.
NOTE: In addition to selecting the predefined buffer sizes from the
Buffer size drop-down list, you can also type in your own custom
value.
