High Performance Browser Networking

Chapter 1. Primer on Latency and Bandwidth

As a result, to improve performance of our applications, we need to architect and optimize our protocols and networking code with explicit awareness of the limitations of available bandwidth and the speed of light: we need to reduce round trips, move the data closer to the client, and build applications that can hide the latency through caching, pre-fetching, and a variety of similar techniques, as explained in subsequent chapters.

结果,提高应用程序的性能,我们需要架构师和优化我们的协议和网络代码明确意识的可用带宽的局限性和光速:我们需要减少往返,移动数据更接近客户,并构建的应用程序可以通过缓存,隐藏延迟预抓取功能,以及各种类似的技术,在后续章节中解释道。
