Bandwidth Test send very slow

RouterOS General
1

Hello,

I have two CCR1009 (with BTest Server enabled) and VM on ESXi (2 vCPU Xeon E5649) with Mikrotik Bandwidth Test.

[CCR1]----100Mbit_WAN----[CCR2]----1Gbit_LAN----(VM)

Bandwidth Test to CCR1 from CCR2 show 94 Mbit send/receive

Bandwidth Test to CCR1 from VM show 94 MBit receive, but only 25…50 Mbit send.

All tests without random data. Why send from VM to CCR1 so slow?

Is the ethernet interface configured exactly how the WAN service specifies it?
(don’t set it to fixed speed or duplex when the service wants automatic or vice-versa!!!)

3

AutoNegotiation on all

4

And is that what the service wants? What is the result of the autonegotiation?

5

no problem in AutoNegotiation
see my first message: Bandwidth Test to CCR1 from CCR2 show 94 Mbit send/receive. Its OK.

Ok let it be clear that there is a mistake in your setup somewhere, CCR can do 10 times that (1 Gbit).
