Testing Data Speed (Throughput Tool)
Throughput is a diagnostic tool that lets you test the data speed on a connection with a remote host. It sends a specified number of IP packets, in a range of packet sizes, to a specified remote computer and calculates the average data speed over the communications link.
To test throughput on a connection:
- From the Tools menu, select Net Tools and click the Throughput tab.
- In the Hostname or IP Address box, type a host name or IP Address (for example, internic.net).
- Set any of the options you want to use:
Packet Count. The number of data packets sent.
Timeout (ms). The time, in milliseconds, that the tool will wait for a response.
Packet Size. The maximum length in bytes of the largest
packet sent. To accurately determine throughput, use the largest packet size that works consistently without timing out.Delay (ms). Number of milliseconds to wait between packets.
TCP. Normally, ICMP packets are sent, but if this is selected, TCP checks are sent through the echo port (port 7), which must be running on the remote system. Throughput is more accurate if this option is not used.
- Click the Start button.
The Throughput tool sends the specified number of data packets, in a range of packet sizes. For each data packet sent, Throughput shows the number of packets sent, the number received by the remote host, and the average time it took to receive a response (in milliseconds).
The data speed (in kilobytes per second or whatever measure is appropriate) on the connection is calculated; this is the "throughput." This will vary depending on the system you are checking and the size of data packets.
During the test, the Start button toggles to Stop. You can click Stop at any time to stop the test. Click Clear to erase the results from the display window.
