Switch Trunk between two CRS125

Hi,

Can I set switch trunk between to CRS125 ?
I have set Port 3-4 on both devices in as switch trunk, but I cannot connect to other device.
When I set up bonding on this ports, it is working, but performance is bad.
I have configuration from http://wiki.mikrotik.com/wiki/Manual:CRS_examples#Trunking

Switch 1

/interface ethernet switch trunk
add member-ports=ether3,ether4 name=trunk1
/interface ethernet
set [ find default-name=ether3 ] master-port=ether1
set [ find default-name=ether4 ] master-port=ether1
/ip address
add address=x.x.x.1/21 interface=ether1 network=x.x.x.0

Switch 2

/interface ethernet switch trunk
add member-ports=ether3,ether4 name=trunk1
/interface ethernet
set [ find default-name=ether3 ] master-port=ether1
set [ find default-name=ether4 ] master-port=ether1
/ip address
add address=x.x.x.2/21 interface=ether1 network=x.x.x.0

Hi,

What is the proper way to create trunk (bonding) between to CRS125 using switch features.
I tried bonding but performance is worst than on single 1GB link (530 Mbits vs 740 Mbits)
