Before revision:  In this paper, as a case study we investigate the challenges raised for conventional operating systems. For typical latency-critical services running with Linux on a 40-core server - a main-stream server hardware system in near future  , we found, when the outlier limit decreases, the outlier proportion of a single server will significantly deteriorate.
After revision:  In this paper, using a typical workload-memcached on a 40-core server - a main-stream server hardware system in near future , we found, when the outlier limit decreases, the outlier proportion of a single server will significantly deteriorate.
