Finding Network Bottlenecks

Use the following counters to identify bottlenecked network resources:

Network Interface\ Bytes Total/sec
Network Interface\ Bytes Sent/sec
Network Interface\ Bytes Received/sec
Protocol_layer_object\ Segments Received/sec
Protocol_layer_object\ Segments Sent/sec
Protocol_layer_object\ Frames Sent/sec
Protocol_layer_object\ Frames Received/sec
For NWLink performance objects, frame-related counters report only zeroes. Use datagram-based counters for these objects.
Server\ Bytes Total/sec
Server\ Bytes Received/sec
Server\ Bytes Sent/sec
Network Segment\ % Network Utilization
