Load averages on Centos7

Hello. I have a vps running Centos7 with 8 cores. When i'm looking at the load averages I get :

1 min	5 min	15 min
0.34	0.29	0.25

It seemed pretty low until I found out that a load average of 1 on a single core actually means a load of 100%... So if I'm not mistaken a load average of (0,29 (5min) x 8 (cores)) x 100 = 232% load average ! I'm I right ? is my vps running at over capacity ? Plus, with the top command, it seems that I have 99ish tasks in queue... Does it mean my vps is not strong enough to run my websites ? Thanks for your help

  From my understanding, load represents the number of processes/threads waiting for CPU. So on your server (with 8 CPU) the load would not truly be 100% unless the load was 8 (which would use all 8 of your CPU's). The load on your server is extremely low IMHO.

  Thanks for your message. I prefer this way, hope you are right ;D. How about the id I get with the top command ? 99 tasks seems pretty high don't you think ?

  @ffeingol is correct - a load of 1 on a multi-core system would indicate that 1 CPU core is fully loaded. Your machine's load looks just fine and is very low. 99 tasks doesn't seem high at all. My personal server with zero activity shows 170 right now. You have to remember that's everything on the machine from the initial boot process all the way to an individual click in WHM or cPanel.
