Hi there,
I've recently bought a Mikrotik CRS125-24G-1S-2HnD routerboard. I've noticed that despite GE ports file transfer within my LAN is very slow. Maximum transfer I've seen was 300 mbps while average is around 150-200 mbps. Sometimes it's under 60 mbps. I can't find the reason for this.

I've tested that with my PC, two laptops and a banana pi board. Tried all the combinations and results are the same. Needless to say all those devices have GE network adapters.

Brief description of my configuration would be a home router with DHCP. All ports are currently bridged (I have also tried default configuration with slave ports- same effect).

RouterOS version is 6.27


Here is a result of a test suggested in another topic(pinging a laptop):
My friend has the very same routerboard also with ROS 6.27 and he says he can easily reach 700-900 mbps speeds in his lan.
Do you guys know what could be wrong? Is this a hardware issue?

You must use master slave for any kind of speed. The CPU of this is quite slow.

Packetloss is solved in 6.28rc.
Try this version: http://www.mikrotik.com/download/share/ ... latest.npk

Hoznam, I've installed 6.28rc20 and the results are:
I've also included a command so you can see if it's correct.

Barkas, I have done that. In conjunction with new version and changing queue to hardware-default it's around 350-400 mbps now. Still, could be better?
