When I run the following command

less  /proc/cpuinfo

I get list of 40 CPUs, does that mean my system can load go up to 40 and things still be running smoothly?

    Your system load (as displayed in `top` or `uptime`) is the queue length, not a measure of how much of the available CPU is in use. If your system load is 40, you are backed up regardless how many CPUs you have. See [this answer](http://unix.stackexchange.com/questions/118124/why-how-does-uptime-show-cpu-load-1) helpfully loaded in the "Related" sidebar atm. – user4556274 Mar 05 '17 at 19:40
  • so the number of cores is not relevant to system load? – Arya Mar 05 '17 at 19:43
  • Uh, it depends. I've seen dual processor solaris systems chugging along without issue at a load of 5000 while a dual processor linux box at that same load was busy corrupting payment batch files. – thrig Mar 06 '17 at 15:06
