With more and more repercussion on all sites, the internet has become a tool that goes beyond simply consuming information, has become an everyday thing that helps us with tasks such as shopping, being in contact with our company remotely or simply giving ourselves a treat from time to time. Like its increasing introduction in most companies and homes, the speed of network connections has also been consistent, although at a slower pace, mainly due to the "low" investment in infrastructure by the companies in charge. to this end.
The problem comes when it does not work as well or as fast as the commercials of the ISP in question have promised us, so we will see if it is the fault of the software we have installed on our Mac or simply that the people of the company in question have made us false promises.
Most of the time, sudden changes in speed are related to latent program update processes that continue to consume network resources without being active. Possibly on our Mac we share equipment with more people and there is an active session trying to update a program or a p2p application such as utorrent or transmission has been running.
To monitor all this activity when we suspect that there is something behind us stealing speed when we need it, we will use the terminal with the command «top», normally this command is related to the activity of Ram, CPU ... but in this case we will combine it with «net ». Thus with the command nettops We will see what is happening, the only problem is that the information provided by this command is too extensive and otherwise we have networking knowledge It may not tell us anything, so if we press the left (left arrow) or right arrow key, we will collapse or display all the information in order to associate it with the specific program and thus know which is the culprit.
