However, performance demands of latency-sensitive applications with very low latency requirements such as distributed in-memory data management, stock trading, and high-performance computing have long been thought to be incompatible with virtualization. vSphere 5.5 includes a new feature for setting latency sensitivity in order to support virtual machines with strict latency requirements." ----- Original Message ----- > From: "Paul Robert Marino" <prmari...@gmail.com> > To: "Nico Kadel-Garcia" <nka...@gmail.com> > Cc: "John Lauro" <john.la...@covenanteyes.com>, "Brandon Vincent" > <brandon.vinc...@asu.edu>, "Lee Kin" > <llwa...@gmail.com>, "SCIENTIFIC-LINUX-USERS@FNAL.GOV" > <scientific-linux-users@fnal.gov> > Sent: Sunday, August 24, 2014 3:27:39 PM > Subject: Re: about realtime system ... > By the way one of those stock exchanges is where the VMware engineers > told us never to use their product in production.
