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?
