Manual:Tools/Speed Test
The Speed Test is an easy test tool for measuring ping, jitter, TCP and UDP throughput from one MikroTik device, to another.
«speed-test» command is based on Ping Tool and Bandwidth Test. In order to use this command — Bandwidth test server needs to be accessible.
General interface properties
Sub-menu: /tool speed-test
| address (IP address; Default: «») | IP address of host |
| connection-count (integer; Default: 20) | If device has more than 20 cores — core count will be used |
| password (string; Default: ) | Password for the remote device |
| test-duration (integer; Default: 10) | Duration for each test (By default: 5 tests * 10 sec duration + 1sec pause between each test = 55sec) |
| user (string; Default: admin) | Remote device username |
Usage example
Bandwidth and speed tests should be conducted through the devices, not on them to ensure real life simulation and not to overload the CPU on the devices under testing,(DUT) due to traffic generating process.
To run a simple test from device A (192.168.88.1) to device B (192.168.88.2):
[admin@MikroTik]] > /tool speed-test address=192.168.88.1 status: done time-remaining: 0s ping-min-avg-max: 541us / 609us / 3.35ms jitter-min-avg-max: 0s / 76us / 2.76ms loss: 0% (0/100) tcp-download: 921Mbps local-cpu-load:30% tcp-upload: 920Mbps local-cpu-load:30% remote-cpu-load:25% udp-download: 917Mbps local-cpu-load:6% remote-cpu-load:21% udp-upload: 916Mbps local-cpu-load:20% remote-cpu-load:6%
If any of device CPU utilization during test reaches 100% warning message will appear:
[admin@MikroTik]] > /tool speed-test address=192.168.88.1 ;;; results can be limited by cpu, note that traffic generation/termination performance might not be representative of forwarding performance status: done time-remaining: 0s ping-min-avg-max: 541us / 609us / 3.35ms jitter-min-avg-max: 0s / 76us / 2.76ms loss: 0% (0/100) tcp-download: 721Mbps local-cpu-load:78% tcp-upload: 820Mbps local-cpu-load:100% remote-cpu-load:84% udp-download: 906Mbps local-cpu-load:10% remote-cpu-load:54% udp-upload: 895Mbps local-cpu-load:55% remote-cpu-load:12%
«test-duration» parameter allows changing duration of all of the 5 tests:
- ) Ping test with 50ms delay
- ) TCP recieve
- ) TCP send
- ) UDP recieve
- ) UDP send
Summary
The Bandwidth Tester can be used to measure the throughput to another 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 data stream. 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 which is usually 1500 bytes. There is no acknowledgment required by UDP; this implementation means that the closest approximation of the throughput can be seen.
- Up to RouterOS version 6.44beta39 Bandwidth Test used only single CPU core and reached its limits when core was 100% loaded.
- Bandwidth Test uses all available bandwidth (by default) and may impact network usability.
- Bandwidth Test uses a lot of resources. If you want to test real throughput of a router, you should run bandwidth test through the tested router not from or to it. To do this you need at least 3 routers connected in chain: the Bandwidth Server, the router being tested and the Bandwidth Client.
- If you use UDP protocol then Bandwidth Test counts IP header+UDP header+UDP data. In case if you use TCP then Bandwidth Test counts only TCP data (TCP header and IP header are not included).

Introduction
The Speed Test is an easy test tool for measuring ping, jitter, TCP and UDP throughput from one MikroTik device, to another. The «speed-test» command is based on the Ping Tool and Bandwidth Test. In order to use this command — Bandwidth test server needs to be accessible.
General interface properties
The speed-test is based on five configurable properties:
- address — IP address of host;
- connection-count — If a device has more than 20 cores — core count will be used (default is 20);
- password — Password for the remote device;
- test-duration — Duration for each test (By default: 5 tests * 10 sec duration + 1sec pause between each test = 55sec);
- user — Remote device username;
Configuration Example
Bandwidth and speed tests should be conducted through the devices, not on them to ensure real-life simulation and not to overload the CPU on the devices under testing,(DUT) due to the traffic generating process.
