Acceptable load average

My Ubuntu server's load is 5-7 most of the times. When the load is about 7 and I check my server response at webpagetest.org I get an F grade (~9 Sec) for 'First Byte Load' while when load is about 4, I usually get A grade for FBL. So I suspect 7 should be an unacceptably high load. Now wondering what range of server loads are generally regarded as normal?

  • There is no "normal" without knowing more about the server and what it's supposed to do for a living. I have an Ubuntu 10 machine serving up 8 websites with about 1500 views a day per site along with file storage, internal dns that shows about 5% use per day - I almost never see 7% load unless updates are running or a backup is being performed. Run htop and watch what is causing the highest load. – Greg Merideth Aug 13 '11 at 23:31
  • It's not a duplicate: 'How high server load go?' is logically a different question. – alfish Aug 13 '11 at 23:35
  • @user88597 Let's put it this way: What figures of server load should be alarming? – alfish Aug 13 '11 at 23:38
  • @James Cpu usage is usually over %70. RAM usage around 7GB. – alfish Aug 13 '11 at 23:47
  • oops, meant to edit my previous comment (I accidentally deleted it). How much RAM do you have, and how many cpu cores do you have? – James Aug 13 '11 at 23:53
  • @James The total RAM is 8GB. The cpu has 4 cores. – alfish Aug 13 '11 at 23:57

It depends on how many CPU or Core you have

2 CPU > 2

4 CPU > 4

2 Core > 2

4 Core > 4

2 CPU (EACH 4 CORE) > 8

4 CPU (EACH 4 CORE) > 16
