OLDIsim & PerfKit open sourced

We have worked with Google to develop Perfkit, a framework for cloud performance benchmarking. One of the most interesting benchmarks in the suite is OLDIsim, that models the distributed, fan-out nature of many modern applications with tight tail latency requirements, such as Google Search and some NoSQL database applications. The original version of OLDsim was developed by David Lo. 

Perfkit and OLDIsim are now open-source on Github.
