Several web application back ends offer a lot of scalability but tax you with high latencies. This can be observed in most cloud based back ends, specially when the application is deployed off the cloud's network. In this presentation we introduce NeverBlock, a library that utilizes light weight concurrency primitives (Fibers) to enable concurrent I/O operations in a seamless manner. We examine the performance and the resource utilization characteristics of various types of application before and after they use NeverBlock.
