[$] Networking and high-frequency trading

The high-frequency-trading (HFT) industry is rather tight-lipped about whatit does and how it does it, but PJ Waskiewicz of Jump Trading came to the Netdev 0x16 conference to tryto demystify some of that, especially with respect to its use ofnetworking. He wanted to contrast the needs of HFT with those of the traditional networkingas it is used outside of the HFT space. He also has some thoughts on whatthe Linux kernel could do to help address those needs so that HFT companiescould move away from some of the custom code that is currently beingdeveloped and maintained by multiple firms in the industry.
