I just got a RB Hex (RB750GR2).
I configured two ports with different VLANs/Net's and routed them accordingly.
When shifting data from VLAN10 to VLAN20, the traffic goes up to ~ 100MBps, though both devices connected are capable of more traffic. At ~100MBps, CPU load is at 100%. The counters in the Firewall view of Winbox show that both devices connect through FastTrack.
Question: normal behaviour or configuration error?
