Optimising Client Side Performance
优化客户端性能
演讲者：颜焜
Intended Audience: Client Programmers
参与人员：客户端程序员
Description: This talk will introduce methods and tools to perform systematic performance analysis. It introduces the profiler and the "fly through" which allow accurate and comparable data to be obtained and analysed. Methods to narrow down the investigation are presented as well as ideas on how to improve problem areas. Finally the Job System is introduced (a BWT 2.0 feature) that makes it easier to use multi-core CPUs.
演讲内容：对进行系统性的性能分析所使用的方法和工具进行介绍。不仅介绍了怎样使用BigWorld引擎内建的性能分析工具和“飞行”模式来得到精确的、可以互相对比的数据以及如何对这些数据进行分析，还介绍了一些可以缩小检视范围的方法以及对查出的问题进 行改善的思路。最后，还介绍了BigWorld引擎2.0 中引入的任务系统（Job System），展示如何使用它让我们更方便地利用多核CPU。
