title: Ultra-low latency programming on Linux, where to begin?
body: <p>I heard there are some ways to modify linux such that an particular application can obtain very low latency such that whenver it ask resources, the OS will try to give it the resource as soon as possible, kind of overriding the default preemptive multitasking mechanism, I dont have a CS background, but the application I am working-on is very latency-sensitive, can anyone tell me are there any docs/stuff on this specific matter? many thanks.</p>
