Group, My linux box, running with Centos-5.5, is showing up (??) a pseudo network interface for Eth0. On Switch where my Eth0 is connected, observed 2 MAC-Addresses. If a DHCP server present in LAN, the second pseudo interface is picking up a DHCP IP Address too. Furthermore you can ping both Eth0 ip and Psedo Eth0 IP from the switch. The intensity of the problem is more when port-security is

...om large workloads, we think the results demonstrated the potential of CSSPGO and served its purpose for proof of concept. We plan to continue tuning and start to evaluate larger internal workloads soon, and we’d like to upstream our work. Feedbacks are welcomed! What is the performance win with peudo-probe alone? [wenlei] We don’t have numbers for pseudo-probe along. As I mentioned earlier, profile quality improvement may not translate directly to perf win without heuristic changes. That’s why we evaluate pseudo-probe exclusively with profile quality metric. The hope is that it will open up op...

Hi All, Our team at Facebook is building a new context-sensitive Sample PGO as an alternative to the existing AutoFDO. We’d like to share our motivation, propose a new design, and reveal preliminary results on benchmarks. We will refer to the proposed design as CSSPGO in this RFC. The new CSSPGO leverages simultaneous LBR and stack sampling to construct a full context-sensitive profile. It
