Like Mike mentioned, the feature list in RouterOS is nothing short of
impressive -- problem is that pretty much everything in there is
inherently buggy.
That and one hell of a painful syntax-schema to work with too.

staggering if you are in the sub 20gig space.

Aren't most of the new whitebox\open source platforms based on switching and not routing?
I'd assume that the "cloud-scale" data centers deploying this stuff still have
more traditional big iron at their cores.
The small\medium sized ISP usually is left behind. They're not big enough to
afford the big new hardware, but all of their user's NetFlix and porn and
whatever else they do is chewing up bandwidth. For example, the small\medium
ISPs are at the Nx10GigE stage now. The new hardware is expensive, the old
hardware (besides being old) is likely in a huge chassis if you can get any
sort of port density at all.
48 port GigE switches with a couple 10GigE can be had for $100. A minimum of 24
port 10GigE switches (except for the occasional IBM switch ) is 30x to 40x
times that. Routers (BGP, MPLS, etc.) with that more than just a couple 10GigEs
are even more money, I'd assume.
I thought vMX was going to save the day, but it's pricing for 10 gigs of
traffic (licensed by throughput and standard\advanced licenses) is really about
5x - 10x what I'd be willing to pay for it.
Haven't gotten a quote from AlcaLu yet.
Vyatta (last I checked, which was admittedly some time ago) doesn't have MPLS.
The FreeBSD world can bring zero software cost and a stable platform, but no
MPLS.
Mikrotik brings most (though not all) of the features one would want... a good enough
feature set, let's say... but is a non-stop flow of bugs. I don't think a week or two
goes by where one of my friends doesn't submit some sort of reproducible bug to Mikrotik.
They've also been "looking into" DPDK for 2.5 years now. hasn't shown up yet.
I've used MT for 10 years and I'm always left wanting just a little more, but it may be
the best balance between the features and performance I want and the ability to pay for
it.

Cumulus Networks has some stuff,

Pretty decent presentation with more details you like.

Hi,
I know that specially programmed ASICs on dedicated hardware like
Cisco, Juniper, etc. are going to always outperform a general purpose
server running gnu/linux, *bsd... but I find the idea of trying to use
proprietary, NSA-backdoored devices difficult to accept, especially
when I don't have the budget for it.
I've noticed that even with a relatively modern system (supermicro
with a 4 core 1265LV2 CPU, with a 9MB cache, Intel E1G44HTBLK Server
adapters, and 16gig of ram, you still tend to get high percentage of
time working on softirqs on all the CPUs when pps reaches somewhere
around 60-70k, and the traffic approaching 600-900mbit/sec (during a
DDoS, such hardware cannot typically cope).
It seems like finding hardware more optimized for very high packet per
second counts would be a good thing to do. I just have no idea what is
out there that could meet these goals. I'm unsure if faster CPUs, or
more CPUs is really the problem, or networking cards, or just plain
old fashioned tuning.
Any ideas or suggestions would be welcome!
