Freddy, did you get your test up ?
I too am facing the same BGP scalability constraints as you are, and the only
real viable solution seems to be filtering.
I'll probably will setup a small test environment to see if this
actually works as expected.
Best Regards,
Freddy

You butt up against major power/heat issues here in a single rack, not
that it's impossible. From what I could find the rPi2 requires .5A
min. The
As it turns out, I've been playing around benchmarking things lately
using the tried and true
UnixBench suite and here are a few numbers that might put this in some
perspective:
1) My new Rapsberry pi (4 cores, arm): 406
2) My home i5-like thing (asus 4 cores, 16gb's from last year): 3857
3) AW
Interesting! Knowing a pi costs approximately $35, then you need
approximately $350 to get near an i5.. The smallest and cheapest desktop
you can get that would have similar power is the Intel NUC with an i5 that
goes for approximately $350. Power consumption of a NUC is about 5x that of
the raspbe

Did I miss anything? Just a quick comparison.
If those numbers are accurate, then it leans towards the NUC rather than
the Pi, no?
Perf: 1x i5 NUC = 10x Pi
$$: 1x i5 NUC = 10x Pi
Power: 1x i5 NUC = 5x Pi
So...if a single NUC gives you the performance of 10x Pis at the capital
cost of

Yeah, missed that.

It's pretty interesting what you can do with immersion cooling. I work
with it at $DAYJOB. Similar to air cooling, but y

Maybe I messed up the math in my head, my line of thought was one pi is
estimated to use 1.2 watts, whereas the nuc is at around 65 watts. 10 pi's
= 12 watts. My comparison was 65watts/12watts = 5.4 times more power than
10 pi's put together. This is really a rough estimate because I got the
NUC's
Rather then guessing on power consumption, I measured it.
I took a Pi (Model B - but I suspect B+ and the new version is relatively
similar in power draw with the same peripherials), hooked it up to a lab
power supply, and took a current measurement. My pi has a Sandisk SD card
and a Sandisk USB
