It has historically been this way. I don't quite understand and definitely don't agree with the reasoning behind this. I also think loadavg should only count processes executing on the CPU. But it doesn't... So forget load average, and only look at cpu utilization. With linux kernel 2.4.22-1.2199.nptlsmp (I know, it's very old) Sometimes Load average increases to big value (over 7) but my 4 vCPU are in idle state (5% busy every cpu).

From your data, since your load avg ~ 24 - 32 and you have 4 cores, the average load / core is ~ 6 - 8 (processes waiting for CPU). Since your CPU utilization is low (69% idle), we can only conclude that you have a large no of threads waiting for I/O to complete (the load avg calculation includes threads waiting for I/O to complete). Follow the steps to reduce load on server. 1. Use following command to check HTTP connections on server. [[email protected] ~]# netstat -antupl | grep http.

The three load average values from left to right represent one-minute, five-minute, and 15-minute averages. Again, speaking very generally, if you see the one-minute average go above the number of physical CPUs you have, then the system is most likely CPU bound. With linux kernel 2.4.22-1.2199.nptlsmp (I know, it's very old) Sometimes Load average increases to big value (over 7) but my 4 vCPU are in idle state (5% busy every cpu).

If the database is hosted in Linux, one can also use the sar command to find the server load average upto a 10 minute granularity.
