Today I will speak about LOAD , uptime , top under your cores..
Let’s get info on each processor in your system
<xmp>$ cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD

You can get LOAD about your cores using some linux commands.
… using top command
<xmp>top - 14:09:52 up 5:48, 1 user, load average: 0.33, 0.34, 0.54
or uptime command:
14:10:37 up 5:49, 1 user, load average: 0.70, 0.42, 0.55</xmp>
Load averages are the three numbers shown you the LOAD averages over periods of time: one, five, and fifteen minute averages.
If you want to produce or to put load on LOAD on core or on more cores , then use this
<xmp>dd if=/dev/zero of=/dev/null</xmp>
… or to make more LOAD
<xmp>dd if=/dev/urandom | bzip2 -9 >> /dev/null</xmp>
This will show you how it’s working your cores.
If the LOAD is between 0.00 and 1.00 means there’s no traffic on the bridge at all.
The LOAD can be 1.00 means the bridge is exactly at capacity of core.
On multi-processor system, the load is relative to the number of processor cores available.
This means the load can be more then 1.00 and will working fine.
For example It’s still healthy with a load of 3.00 if you have a quad-processor system.
If you have also one core and the load is 1.70 this means the core is full (1.00) and 0.70 will wait the capacity of core to be released.
