# Mixing Task Ranks
|
|
|
Although by default Linktest tests the connection between a given task, which has a number associated with it called the rank, and all other tasks results may depend on the order in which the testing is performed. The `--mix` command-line option causes the task ranks to be randomly mixed which means that consecutive runs will test physical connections in a different order.

# Number Of Messages
|
|
|
Linktest benchmarks communications by repeating a communication many times. The amount of times it repeats the sending of messages for timing purposes is controlled via the `--num-messages` command-line argument. This defines how many times the back-and-forth sending of messages is repeated for timing purposes. The final returned times are the average time it took the message to be sent back-and-forth.
