I know it’s been a while since I last had a chance to share my thoughts on this site, but I couldn’t resist this one.  Cisco recently announced its “End-to-End High-Performance Trading Fabric.”  A couple of things about this announcement struck me as particularly interesting. 

First, it doesn’t appear that there is any real news here other than the fact they released performance figures for their Nexus 3068 switch.  It is so unlike Cisco to publicize its performance data; low latency of its switches is not one of their strengths. Cisco has not published performance numbers on the Nexus 5548 and for a good reason. The 5548’s performance on packets sizes of 512B and less is egregious.
