The Bandwidth Tester can be used to monitor the throughput only to a remote MikroTik router (either wired or wireless) and thereby help to discover network ‘bottlenecks’.
The TCP test uses the standard TCP protocol with acknowledgments and follows the TCP algorithm on how many packets to send according to latency, dropped packets, and other features in the TCP algorithm. Please review the TCP protocol for details on its internal speed settings and how to analyze its behavior. Statistics for throughput are calculated using the entire size of the TCP packet. As acknowledgments are an internal working of TCP, their size and usage of the link are not included in the throughput statistics. Therefore this statistic is not as reliable as the UDP statistic when estimating throughput.
The UDP tester sends 110% or more packets than currently reported as received on the other side of the link. To see the maximum throughput of a link, the packet size should be set for the maximum MTU allowed by the links – usually this is 1500 bytes. There is no acknowledgment required by UDP; this implementation means that the closest approximation of the throughput can be seen.

The Bandwidth Test feature is included in the 'system' package. No installation is needed for this feature
!Caution! Bandwidth Test uses all available bandwidth (by default) and may impact network usability.
There is no other significant resource usage.

unwanted bandwidth wasting. Note that remote router must be MikroTik router in
order to run the test.

Run TCP or UDP bandwidth test. Tries to use maximum or partial amount of
bandwidth to test link speed. Note that remote router must be MikroTik router
in order to run the test. Be aware that default test uses all available
bandwidth and may impact network usability.

direction - specify the direction of the test (receive, transmit, both, default is transmit)
do - Script source
duration - Duration of the test
interval - Delay between messages (in seconds). Default is 1 second. Can be 20ms...5s
local-tx-speed - Transfer test maximum speed (given in bits per second)

protocol - Type of protocol to use (UDP or TCP, default TCP)
remote-tx-speed - Receive test maximum speed (given in bits per second)
size - Packet size in bytes (50..1500, default 512). Works only with UDP protocol
user - Remote user
