在我理解看来,Graphics是一个device context和你的drawing conetent之间的一个中介.它存储了device context的相关属性,以及drawing content的属性.这样,它就能用自己的方法把drawing content“映射”到device content 之上.GDI中的绘图工作是直接在device context之上进行的.在GDI—+中,你因该在device context之上再建立一个graphics,然后调用graphics的相关方法完成绘…

什么是CPU上下文切换? 现在linux是大多基于抢占式,CPU给每个任务一定的服务时间,当时间片轮转的时候,需要把当前状态保存下来,同时加载下一个任务,这个过程叫做上下文切换.时间片轮转的方式,使得多个任务利用一个CPU执行成为可能,但是保存现场和加载现场,也带来了性能消耗.  那线程上下文切换的次数和时间以及性能消耗如何看呢?                ​    ​如何获得上下文切换的次数? vmstat直接运行即可,在最后几列,有CPU的context switch次数. 这个是系统层…
