Our results indicate that heavy network usage from competing VMs can introduce delays as high as 100 ms to round-trip times. Furthermore, virtualization adds most of this delay when sending packets, whereas packet reception introduces little extra delay. Based on our findings, we discuss guidelines and propose a feedback mechanism to avoid measurement bias under virtualizationen-USArticle
