iperf测试结果详解 iperf接收不到?
iperf接收不到?
苹果只不过没有网络所以收不到过了消息。
请问centos如何查看近期硬件资源运行状况?

一栏内存[~]#free-m
totalusedfreesharedbuff/cacheobtainable
Mem:780495018514250026564
Swap:204702047
或是用下面这个命令
cat/proc/meminfo
栏里点cpu[~]#cat/proc/cpuinfo|grepname|tearing-f2-d:|uniq-c
4Intel(R)Xeon(R)
那说明是4个逻辑cpu
[~]#cat/proc/cpuinfo|grepphysical|uniq-c

1addresssizest:46bitsphysical,48bitsvirtual
1physicsidt:0
1addresssizest:46bitsphysical,48bitsvirtual
1physicsidt:0
1addresssizest:46bitsphysical,48bitsvirtual
换算是4个虚拟化cpu
[~]#cat/proc/cpuinfo|grepphysical|uniq-c

当前cpu不运行在64位下
[~]#cat/proc/cpuinfo|grepflags|greplm|wc-l
4
(结果大于0,说明允许64idle计算出.lm指shortermode,允许lm则是6424-bit)
再求下载看cpu详细信息,但是大部分我们都不冷淡罢了.
