If you want to carry out an analysis of your network performance , then a good place to begin is by using the perfmon.exe tool. There are a lot of network related performance counters to measure. Depending on the analyzing parameter we need to select their respective counters. Below table gives a brief of how those counters can be utilized for analysis of various network objects.
| Object | Analyzing Parameter | Counter |
| IPV4, IPV6 | Resource Utilization | Datagram Received/Sec , Datagram Sent/sec |
| TCPV4, TCPV6 | Resource Utilization | Segments Received/Sec, Segments Sent/Sec, Segments Retransmitted/Sec |
| Network Interface | Resource Utilization | Bytes Received/Sec, Bytes Send/sec, Packets Received/sec, Packets Sent/sec, Output Queue Length |
| Processor Information | Resource Utilization | % Processor Time, Interrupts/sec, DPCs Queued/Sec |
| Network Interface | Potential Network Problems | Packets Received Discarded, Packet Received Errors, Packets Outbound Discarded, Packets Outbound Errors |
| WFPV4, WFPV6 | Potential Network Problems | Packets Discarded/sec |
| UDPV4, UDPV6 | Potential Network Problems | Datagrams Received Errors |
| TCPV4, TCPV6 | Potential Network Problems | Connection Failures, Connection Resets |
| Network QoS Policy | Potential Network Problems | Packets Dropped |
| Per Processor Network Interface Card Activity | Potential Network Problems | Low Resource Received Indications/sec , Low Resource Received Packets/sec |
| MS Winsock BSP | Potential Network Problems | Dropped Datagrams, Dropped Datagrams/sec, Rejected Connections, Rejected Connections/Sec |
| Network Adapter | RSC Performance | TCP Active RSC Connections, TCP RSC Average Packed Size, TCP RSC Coalesced Packets/Sec, TCP RSC Exceptions/sec |
