Over 65% of LAN traffic has packet size of < 64 bytes

Just connected a sniffer to our network and noted that over 65% of the packets were < 64 bytes.All our desktop pc's are 100 mbs, Server nics and Switches are 100 and 1000 mbs. With ethernet packets running over 1500 bytes today, my concern or question is that this network might be inefficient?

Thanks for some response.

Re: Over 65% of LAN traffic has packet size of < 64 bytes

An ethernet frame that is less than 64 bytes is considered a Runt. Apart from the network functioning inefficiently, it might also be a concern for excessive collisions since Runts are usually caused by collisions. This can be caused by duplex mismatch and physical problems such as a bad cable, port, or NIC on the attached device.
