If you're experiencing slowness, a quick way to see if you're experiencing high load is using the uptime command. Here is an example:
# uptime
20:20:24 up 19 days, 5:04, 1 user, load average: 1.03, 2.04, 4.05
The averages are:
1.03 (103%) - Average load over the last minute
2.04 (204%)- Average load over the last 5 minutes
4.05 (405%) - Average load over the last 15 minutes
1 cpu core is equivilent to 100% usage.
To understand these load averages, you will need to know how many CPU cores you have. You can find that with the command:
# grep processor /proc/cpuinfo -c
2
With the command output, we can see two cores, so anything over 200% would be considered a high load average.
To track the processes using the high load, you can use the ps or top command. We have articles that explain how to do that here:
For additional assistance, you will want to contact your System Administrator or hire a qualified System Administrator.
