to eliminate name resolutionUsing port 443:
traceroute -T -O info -p 443 hostname.domain.tld tcptraceroute hostname.domain.tld 443
This will also illuminate asymmetrical routing:
tracepath hostname.domain.tld

Start the iperf
server:
iperf -s
Windows firewall:
New-NetFirewallRule -DisplayName 'iPerf-Server-Inbound-TCP' -Direction Inbound -Protocol TCP -LocalPort 5201 -Action Allow | Enable-NetFirewallRule New-NetFirewallRule -DisplayName 'iPerf-Server-Inbound-UDP' -Direction Inbound -Protocol UDP -LocalPort 5201 -Action Allow | Enable-NetFirewallRule
Start the iperf
client and point it at the IP address of the iperf
server:
iperf -c 192.168.1.70
Sample results:
------------------------------------------------------------ Client connecting to 192.168.1.70, TCP port 5001 TCP window size: 64.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.0.201 port 49269 connected with 192.168.1.70 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.1 sec 25.5 MBytes 21.2 Mbits/sec
Changing the iperf
options will modify the parameters of the testing.
For help on options type:
iperf --help
This is an example of options that fully test a Gigabit network by changing:
iperf -c 192.168.1.2 -w 512k -l 512k -P 5
iperf -s -w 512k -l 512k

Make sure your testing client and server have Gigabit NICs (don't ask me how I know).
Server:
iperf -su
Client:
iperf -c 192.168.2.50 -u -b 1G -P 10

Note Unless you have a large RAID array hard disks will not fill a 10Gb pipe. For complete testing a RAMDisk formatted for 12GB is necessary.
ntttcp.exe -r -m 16,*,192.168.0.140 -l 128k -a 2 -t 20
ntttcp.exe -s -m 16,*,192.168.0.140 -l 128k -a 2 -t 20
Note The receiver machine in this case has an IP address of 192.168.0.140. You must specify the receiver’s IP address on the server instance.
