One of the less known advantages of the Turris router is the possibility to verify quality of Internet connection, the so-called QoS (Quality of Service), i.e. especially to measure the download and upload speed, IPv6 support, DNSSEC and parameters connected with net neutrality. Such a measuring may serve to analyse the use of the line and to evaluate whether paying a high speed fee is unnecessary. The experience of the Turris router users shows that the majority of their time online is spent in the slowest zone (0-250 kbps). Moreover, even when the majority of data is transferred in higher speed, fast operation may have only a tiny representation from the time´s point of view. Especially those who do not spend a lot of time watching videos pay extra for high speed connection for a relatively short time of use, mainly for the moments it takes to load a page or download and send an e-mail.
