Making coroutines fast - RethinkDB
Previously, I wrote about using coroutines in RethinkDB. Coroutines are a nice alternative to callbacks because they are easier to program in, and they are a nice alternative to threads because of their greater performance. But how fast are they? Just using an off-the-shelf library like libcoroutine isn’t as fast as you might think. The graph below shows the huge performance degradation of a naive
Intel's Haswell CPU Microarchitecture
Pages: 1 2 3 4 5 6 Over the last 5 years, high performance microprocessors have changed dramatically. One of the most significant influences is the increasing level of integration that is enabled by Moore’s Law. In the context of semiconductors, integration is an ever-present fact of life, reducing system power consumption and cost and increasing performance. The latest incarnation of this trend i
