这个文档中p33~p34页说的我有点不明白?
原文如下:
“The adaptive partitioning thread scheduler throttles CPU usage by measuring the average CPU usage of each partition. The average is computed over an averaging window (typically 100 milliseconds), a
value that is configurable.”------这个明白
“The window size defines the averaging time over which the thread scheduler attempts to balance the partitions to their guaranteed CPU limits. You can set the averaging window size to any value from 8 milliseconds to 400 milliseconds.”
以上是说: adaptive partitioning线程调度器通过测量每个partition的CPU平均使用率来控制的,而这个平均值是通过“ an averaging window”被计算。然后呢,window size 定义 an averaging time。
后面的文档又讲到:
“Window 2 Typically 10 times the window size.
Window 3 Typically 100 times the window size.”
这个Window 2和Window 3是什么??
跟Averaging window又有什么关系,看的云里雾里的。
请指教,谢谢
