-If there are many lines, it updates the data as fast as possible with each time.
-It is very fast you can be either be synchronized or using **-p** to requiert a minimal time between each update.
-You can also use a first column describing the time in µs to read the line.
-Finaly you can limit the number of line read by using -n.
