When it comes to comparing network/embedded CPUs, there is more than
just MHz that needs to be considered. Some CPUs have multiple cores,
hardware accelerators, etc. For example, we use a Gemini SL3512 CPU in
some of our products. Here are some of the accelerators that it has:

Ok guys. Great feedback on all of this, but back to my original question,
what's the max throughput I could expect from a RB532A? If there was an
answer my spam filter must have gotten it.
NAT'ing going on with 3 desktop systems. Other than that, no queueing, no
firewalling, no routing, etc
From lots of experience, I can tell you that you are just going to have to
test it with your configuration. Each version of Mikrotik is different
and can radically affect performance. They make so many changes that
aren't included in the changelog, you have no idea if they made a change
to NAT
If you aren't doing wireless then 40Mbps should be easily achievable. If you
don't gets the expected results then kill connection tracking in the
firewall and retest.

Does anyone know of a switch with GigE ports and the capability for 10GigE
uplinks without routing?
I want a switch that can upgrade the core links when necessary, but not wanting
one that routes because I'm under the impression that Layer 3 switches don't
perform well.

Yes. The page is VERY well written. It sounded almost word-for-word like
the way I've been teaching this concept (along with many others) to the
WISP industry since 2001.

Worthy to note, in my opinion the value of the 532a was the daugherboard to

ports), and with greater than 200Mhz CPU processing to handle the
I agree fully with these analagees, but...
I was more specically asking what was better about the chip designs.
I can compare the design of a Celeron4 to a Pentium4, and know exactly why
the Pentium was a faster chip for some type applications.
(front side Bus speed, larger level1 cache, etc)
Processor speed is only part of the answer to the RISC, CISC battle and this
type of radio design. Things flow in a logical operation and waiting occurs
on the systems buses in the PC based design.

Thanks for the vote of support Dylan. I recently looked at Grass's feature
