"Hey a biased analysis, IIRC AMS-IX allows all kind of traffic including

CIXes in US behave similar. Besides that, I wonder what kind of hardware
will they be using in the future, assuming they grow like all other
CIXes...."
AMS-IX allows the exchange of IPv4 and IPv6 traffic and doesn't mind
whether you pay to receive certain prefixes. At any IXP, you can only
send traffic towards peers that actually announced the netblocks to you
[give or take next-hop fudging that some allow and some disallow].

There is no "fair" stat, since you cannot quantify an IX into a
single dimension.
Equinix Ashburn almost certainly carries more traffic through the
building than AMS-IX carries, probably by many times, but that stat
is not published as most of the traffic is over PI.
Excellent example on why this is not a fair comparison, as Equinix
Ashburn is a building and AMS-IX is a collection of Ethernet switches. :-)
Given that the internal sequential numbering for fibers at NIKHEF (one
of four housing sites with an AMS-IX switch) runs into the thousand,
I'm willing to believe that the amount of traffic exchanged over private
interconnects at all four locations is significant, if not way bigger
than what's sent across the AMS-IX platform.
All that said, AMS-IX is an outstanding IX. A network with
significant European traffic is almost certain to find peering at
AMS-IX beneficial. But the same is true for other exchanges (e.g.
LINX).
Thanks, Patrick.
