If you wanted raw memcached performance there was an awesome paper on using an FPGA tied to 24GBs of regular DDR3 RAM and a 10G ethernet port. The result was a memcached server with 3.5 to 4.5 microsecond response time, capable of saturating the 10G port even with tiny key-value pairs, and 13 million requests per second while using 50W of power to do so. http://0b4af6cdc2f0c5998459-c0245c5c937c5dedcca3f1764ecc9b2f.r43.cf2.rackcdn.com/11566-hotcloud13-blott.pdf http://0b4af6cdc2f0c5998459-c0245c5c937c5dedcca3f1764ecc9b2f...
