摘要: In a virtual machine (VM) consolidation environment, it has been observed that CPU sharing among multiple VMs will lead to I/O processing latency because of the access experienced by each VM. this paper, we present vTurbo, system accelerates for offloading designated core. More specifically, core - called turbo runs with much smaller time slice (e.g., 0.1ms) than cores shared production VMs. Most IRQs be delegated more timely processing, hence accelerating Our experiments show vTurbo significantly improves VMs' network and disk throughput, which consequently translates into application-level performance improvement.
