Analysis of RB1200 and RB1100, thoughts? Responses?

I’ve had a chance to hook these thing up to some really fast connections, and after gathering enough throughput data I have a theory on how the mikrotik works. It’s important to me as I’m trying to build the highest throughput network possible, and I have a lot of 1200s out there, moving to the 1100s with build out.

It seems to me that the port 9 and 10 flaw on the RB1100 is quite interesting as it surpasses the binary number 0x7 (8). I’ve noticed the real world capabilities of the 1200 to hover just north of 125mb, and the 1100 just north of 250mb (binary 0x3, or 4). It makes me wonder if the ports are multiplexed (IE not true ports, but 4 ports that share a single one via benefit of high speed shift registers or what not). With the RB1200, it’s likely that it has 2 true ports multiplexed 4 ways to make 8, and 2 bastard ports (9 and 10) to hide the fact. With the RB1100, it’s likely to mimick this with 8 real ports, multiplexed 2 ways (other than 3 of them), which explains the orientation of the ports and their capabilities (in theory, I have one on the way to test).

The future for mikrotik as it would seem, is to give each port a processing unit, and then a backbone bus between the port’s processing units, using the “master” port to regulate backbone communications.

How far off base am I here?

I found the following page quite educating as to how to best associate ports on this gear (RB1100) for best common practice:

I think you are overcomplicating things..

The CPU has 3 built-in gigabit network interfaces: The first two are connected to two seperate switchchips and make up for ports 1-4 and 5-8. The 3rd is directly connected to port 11. Then there are 2 gigabit network interfaces connected to the 2 PCIe interfaces of the CPU: port 12 and 13.

I don’t understand why these ports are not seen as ‘fast’ ports on the wiki page. As a PCIe port is fast enough to saturate a gigabit link ports 12 and 13 should be just as fast as port 11.
