Responsiveness without interrupts
Dejan Perkovic, Peter J. Keleher · 1999
this paper is a characterization of the delays actually observed in a suite of applications. We show that the majority of notification delays result from a small number of large delays. These delays can dominate any gains achieved through use of new network technologies. The impact of these delays can be considerable. Our applications averaged more than 31% slower without interrupts than with them. This result argues that the problem is serious, and needs to be addressed either by including interrupts in emerging standards, or through use of the techniques discussed below
