Network Bottlenecks
Network Interface\ Bytes Total/sec - is the rate at which bytes are sent and received over each network adapter;Network Interface\Bytes Total/sec is a sum of Network Interface\Bytes Received/sec and Network Interface\Bytes Sent/sec
Network Interface\ Bytes Sent/sec - this counter is self evident
Network Interface\ Bytes Received/sec - this counter is self evident
Network Interface\ Current Bandwidth - is an estimate of the current bandwidth of the network interface in bits per second (BPS). For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this value is the nominal bandwidth.
Network Interface\ Bytes Sent/sec - this counter is self evident
Network Interface\ Bytes Received/sec - this counter is self evident
Network Interface\ Current Bandwidth - is an estimate of the current bandwidth of the network interface in bits per second (BPS). For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this value is the nominal bandwidth.
UDP\ Datagrams Received/sec - the rate at which UDP datagrams are delivered to UDP users
UDP\ Datagrams Sent/sec - is the rate at which UDP datagrams are sent from the entity.
TCP\ Segments Sent/sec - is the rate at which segments are sent, including those on current connections, but excluding those containing only retransmitted bytes
TCP\ Segments Received/sec - is the rate at which segments are received, including those received in error. This count includes segments received on currently established connections
UDP\ Datagrams Sent/sec - is the rate at which UDP datagrams are sent from the entity.
TCP\ Segments Sent/sec - is the rate at which segments are sent, including those on current connections, but excluding those containing only retransmitted bytes
TCP\ Segments Received/sec - is the rate at which segments are received, including those received in error. This count includes segments received on currently established connections
Server\ Bytes Total/sec - the number of bytes the server has sent to and received from the network. This value provides an overall indication of how busy the server is
Server\ Bytes Received/sec - this counter is self evident
Server\ Bytes Transmitted/sec - this counter is self evident
Server\ Bytes Received/sec - this counter is self evident
Server\ Bytes Transmitted/sec - this counter is self evident
Network Interface\Output Queue Length - is the length of the output packet queue (in packets). If this is longer than two, there are delays and the bottleneck should be found and eliminated, if possible. Since the requests are queued by the Network Driver Interface Specification (NDIS) in this implementation, this will always be 0.
Network Interface\Packets Outbound Discarded - is the number of outbound packets that were chosen to be discarded even though no errors had been detected to prevent transmission. One possible reason for discarding packets could be to free up buffer space.
Network Interface\Packets Outbound Errors - is the number of outbound packets that could not be transmitted because of errors.You should check if someone upgraded the network driver recently.
Network Interface\Packets Received Discarded - is the number of inbound packets that were chosen to be discarded even though no errors had been detected to prevent their delivery to a higher-layer protocol. One possible reason for discarding packets could be to free up buffer space.
Network Interface\Packets Received Errors - is the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.
