In the eventuality that you are sharing a MikroTik router with other users or you are a network administrator, then you might be interested in discovering bottlenecks in the LAN and fix them accordingly.

BTest is a small piece of software that enables you to determine the maximum traffic that can pass through the connection points of a wired or wireless router for the purpose of identifying possible conditions in which the data flow is limited due to the network resources.

The utility enables you to perform the bandwidth test on both the TCP and UDP protocols. Since the TCP tests results do not include data on the size and usage of the data stream in the throughput log, it means that the statistic is not always reliable.

In case you need to retrieve more accurate information on the closest approximation of the performance, then it is recommended to perform UDP tests. You can specify the direction of the traffic to be generated, namely upload, download as well as the send and received packages.

It is necessary to mention that during the tests only a single core of the CPU is employed and that the bandwidth tests cannot exceed the potential of a 100% full core. At the same time, performing the tests means that you allow the application to use all the available bandwidth. Consequentially, you should keep in mind that you may not be able to use your Internet while BTest is actively measuring the bandwidth.
