t1～t2 时间段的 CPU 执行时间: t1 = (user1 + nice1 + system1 + idle1 + iowait1 + irq1 + softirq1) t2 = (user2 + nice2 + system2 + idle2 + iowait2 + irq2 + softirq2) t = t2 - t1 1. 2. 3. t1～t2 时间段的 CPU 空闲使用时间: idle = (idle2 - idle1) 1. t1～...
system(通常缩写为 sys),代表内核态 CPU 时间。 idle(通常缩写为 id),代表空闲时间。注意,它不包括等待 I/O 的时间(iowait)。 iowait(通常缩写为 wa),代表等待 I/O 的 CPU 时间。 irq(通常缩写为 hi),代表处理硬中断的 CPU 时间。 softirq(通常缩写为 si),代表处理软中断的 CPU 时间。 -steal(通常...

idle =idle(t2) – idle(t1) 1. 2. 3. 由于CPU利用率随时间改变,因此对于显示出的CPU利用率,需要随时更新,我设置为1秒更新一次。 (2). 内存信息模块 相对于CPU来说,内存部分的信息较为简单,上表中内存的信息在文件”/proc/meminfo”中对于的字段即可以寻找到。此外还需要计算内存和交换分区的使用率,内存...
The numbers above are obtained on an idle system. Tasks heavily using a processor cache, such as video playback, can greatly degrade hashrate. Optimal number of threads depends on the size of the L3 cache of a processor, 1 thread requires 2 MB of cache. Maximum performance checklist Idle ...
