CIFS vs NETBIOS & network performance

Labnuke99 — Thu, 02 Jun 2011 19:12:38 +0000

Testing file open performance across a WAN vs LAN. I open a 1MB .rtf file. When opening on the LAN, the traffic is on port 445 (CIFS). When opening the same file from the same server across the WAN, the traffic is on port 139 (NETBIOS).

My question for all of you protocol gurus:
Is there really any difference in the traffic when using a different port to do the same activity? If so, what are those differences & how does it contribute to end-user experience?

Some other information you might be interested in:

Number of packets
LAN – 1,544
WAN – 1,864
Size of data packets
LAN – 1,474 bytes
WAN – 1,354 bytes
Time to open (first packet to last packet)
LAN – 3 secs
WAN – 19 secs
