简单理解,slab就是内核维护的一组大小不同的空闲链表,Linux把每个空闲链表 称为后备高速缓存 ( lookaside cache ),当需要使用时,可以从中取出需要的内存块,不用时,再把内存块归还给slab。

To speed up address translation, there is a processor-on-a-chip (PoC) cache and associated logic called translation lookaside buffer (TLB).
为了加快地址转换,架构中有一个 processor-on-a-chip (PoC) 缓存和相关的转换后备缓冲器 (TLB) 逻辑。
The profiling table provides the percentage and number of samples collected for specified processor events such as the number of cache line misses, Transition Lookaside Buffer (TLB) misses, and so on.
评测表提供为特定的处理器事件收集的采样的百分数或数量,比如高速缓存线路故障的数量、传输后备缓存(TLB)故障的数量,等等。
