CPU

lscpu shows the details about the CPU('s) . There are Core(s) per socket and Thread(s) per core. Cores are the hardware processors. Those cores can run more than one thread.

cat /proc/cpuinfo returns everything about your CPU.

The bogomips line tells something about its performance measured and required during kernel boot. The MIPs (million instructions per second) value is therefore bogo.

cat /proc/cpuinfo | grep bogo

bogomips : 3979.99

For performance measurements programs as sysbench are more suitable: sysbench --test=cpu run

Checkout the flags line

cat /proc/cpuinfo

flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mp mmxext 3dnowext 3dnow up ts

To enable those things use ufed to turn on the corresponding use flags and have higher performance.

emerge --update --deep --newuse world

Check out gcc so it compiles with the right flags.
