I'm using it for a core router with 1gbps traffic, serving 800 clients, meaning many thousands of packets per second. My current CCR 1016 is showing around 36k p/s on the main WAN interface. And one of the CPU cores are 95% usage all the time, while the others are around 0 to 20% used.
When you say a STRONG
Xeon what do you mean? 2.5ghz? like: Xeon E5420 Core2Quad @ 2.5GHz?
The router functions as:
PPPOE server using external radius on about 9 interfaces (VPLS and VLANS included)
Shaping router (simple queues)
Simple firewall and mangle rules like blocking address lists and redirecting DNS to self, port forwarding, NAT etc.
about 10 VPLS tunnels. OSPF enabled
Thats about all..
Cores. CCR is pure core quantity.
That said, most tasks in RouterOS are single threaded so I'd argue that a strong Xeon would wipe the floor with Tilera in some applications. What are you planning on using the router for is the ultimate question?
Are we talking as an Edge router or Firewall protecting a lot of users? How many for example?
