这个话题我在这里聊过好多此了。
可是总不能找到我想要的答案。谢谢各位高手！
mpstat 3 9
这个命令输出的结果我想好多  各位   都是用过的。问题是结果能给我们带来什么呢。谢谢！
谢谢！高手指点！

race

mpstat reports the following:

CPU: Processor ID
minf: Minor faults
mjf: Major faults
xcal: Processor cross-calls (when one CPU wakes up another by interrupting it). If this exceeds 200/second, the application in question may need to be examined.
intr: Interrupts.
ithr: Interrupts as threads (except clock).
csw: Context switches
icsw: Involuntary context switches (this is probably the more relevant statistic when examining performance issues.)
migr: Thread migrations to another processor. If the migr measurement of mpstat is greater than 500, rechoose_interval should be sent longer in the kernel.
smtx: Number of times a CPU failed to obtain a mutex.
srw: Number of times a CPU failed to obtain a read/write lock on the first try.
syscl: Number of system calls.
usr/sys/wt/idl: User/system/wait/idle CPU percentages.
