Manual:Performance Testing with Traffic Generator
Summary
RouterOS Version 6 introduced new tool "traffic generator", which allows to perform performance testing without expensive testing hardware. Traffic is generated from one more router in the network.
This article shows necessary configuration and hardware to perform the same tests published in www.routerboard.com.

Routing Performance Testing
DUT Config
/ip address add address=1.1.1.254/24 interface=ether1 network=1.1.1.0 add address=2.2.2.254/24 interface=ether6 network=2.2.2.0 add address=3.3.3.254/24 interface=ether11 network=3.3.3.0
Traffic Generator Config
/ip address add address=1.1.1.1/24 interface=ether1 network=1.1.1.0 add address=2.2.2.2/24 interface=ether6 network=2.2.2.0 add address=3.3.3.3/24 interface=ether11 network=3.3.3.0 /tool traffic-generator packet-template add name=r12 header-stack=mac,ip,udp ip-gateway=1.1.1.254 ip-dst=2.2.2.2 add name=r13 header-stack=mac,ip,udp ip-gateway=1.1.1.254 ip-dst=3.3.3.3 add name=r21 header-stack=mac,ip,udp ip-gateway=2.2.2.254 ip-dst=1.1.1.1 add name=r23 header-stack=mac,ip,udp ip-gateway=2.2.2.254 ip-dst=3.3.3.3 add name=r32 header-stack=mac,ip,udp ip-gateway=3.3.3.254 ip-dst=2.2.2.2 add name=r31 header-stack=mac,ip,udp ip-gateway=3.3.3.254 ip-dst=1.1.1.1
Note: To force MAC address re-discovery (on device/configuration change, just apply emply "set" command to necessary packet-templates)
Running Tests
/tool traffic-generator quick tx-template=r12,r13,r21,r23,r31,r32 packet-size=60 mbps=300
We are specifying 60byte packet in traffic generator to get 64 byte packet on ethernet.
Do the same with different packet sizes:
/tool traffic-generator quick tx-template=r12,r13,r21,r23,r31,r32 packet-size=508 mbps=500 /tool traffic-generator quick tx-template=r12,r13,r21,r23,r31,r32 packet-size=1514 mbps=500
Note: mind that speed in quick mode is specified per stream, so if you have two streams per port, you need to send 1/2 of traffic per stream
