2012 Red Hat Summit: Achieving top network performance

In this session, Mark Wagner reviews enhancements in Red Hat Enterprise Linux 6 and show attendees how to take advantage of them in their environments. Mark uses test results from Red Hat's performance lab to highlight the various differences, advantages, and tradeoffs for many technologies, including Kernel-based Virtual Machine (KVM) virtualization technology, 10Gbit Ethernet, Infiniband, FCoE, Packet Flow Control, and RDMA. Mark also presents guidelines and tools for planning and tuning network configurations for low latency and high throughput. He covers the differences between tuning for baremetal, a KVM guest, a Red Hat Storage file system, and NFS. He also touches upon some tricks developers can use when writing network-based applications.
