[$] Networking and high-frequency trading

Post Syndicated from original https://lwn.net/Articles/914992/

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