i have configured my Mk-CRS326 3 VLAN
networks
10.1.1.0/24 vlan1001
10.2.1.0/24 vlan1002
10.3.1.0/24 vlan1003

All ports are Hw on a bridge. When tranfer some file from the network 10.1.1.0/24 i got 1Gbps tranfer. ( 10.1.1.24 to 10.1.1.25)
When i tranfer from 10.1.1.0/24 to 10.2.1.0/24 just got 100mb and i see trafic on FP-Tx,FP-Rx.

this performance it ok? i miss something on my config?

According to official test results, your switch could realistically route at around 270 Mbps give or take (I'm assuming your device is the one with RJ45 ports). So 100Mbps you're seeing is not far off.
With ROS v7 your unit will be able to offload routing to hardware in certain conditions and that will allow wirespeed routing. Read about L3 HW offloading.
