On modern processors, the cost of a cache miss is significant, so if the language and runtime can help your program achieve better data locality, performance will be improved.
在现代的处理器上,缓存遗漏的成本非常显著,所以如果语言和运行时能够帮助程序实现更好的数据位置,就会提高性能。
If the data is not in the cache, then you have a cache miss and you have to get the item from disk, at disk speed (tens of milliseconds).
如果缓存中没有数据,那么就是缓存未命中(cache miss),必须从磁盘中以磁盘速度(几十毫秒)获取项。
If a D-cache miss (the processor fails to find data in the D-cache) occurs, an interrupt is raised so that the corresponding register can record this event by increasing its value.
如果发生D -cache失效(处理器无法在D - cache中找到数据),那么发出一个中断,让相应的寄存器可以通过增加它的值记录这一事件。
