4.5.4: Throughput

Run the ttcp network benchmark program. Transfer large amounts of data (100's of megabytes) to and from the target system.

The procedure for testing throughput from a host to an RTEMS target is as follows:

1. Download and start the ttcp program on the Target.
2. In response to the ttcp prompt, enter -s -r. The meaning of these flags is described in the ttcp.1 manual page found in the ttcp_orig subdirectory.
3. On the host run ttcp -s -t <<insert the hostname or IP address of the Target here>>

The procedure for testing throughput from an RTEMS target to a Host is as follows:

1. On the host run ttcp -s -r.
2. Download and start the ttcp program on the Target.
3. In response to the ttcp prompt, enter -s -t <<insert the hostname or IP address of the Target here>>. You need to type the IP address of the host unless your Target is talking to your Domain Name Server.

To change the number of buffers, the buffer size, etc. you just add the extra flags to the -t machine as specified in the ttcp.1 manual page found in the ttcp_orig subdirectory.
