How do I find out what is causing high server load?
How To Investigate A High Server Load
- Current CPU Usage. The real-time CPU usage can be viewed by running the “top” command.
- Historical CPU Usage. As noted above, we will use the “sar” command to view the historical statistics.
- Current RAM Usage.
- Historical RAM Usage.
- Current Disk I/O Usage.
- Historical Disk I/O Usage.
Why is my load average so high?
If you spawn 20 threads on a single-CPU system, you might see a high load average, even though there are no particular processes that seem to tie up CPU time. The next cause for high load is a system that has run out of available RAM and has started to go into swap.
How do you troubleshoot on the server if CPU load is high and what action should be taken?
Let’s go over the steps on how to fix high CPU usage in Windows* 10.

- End or Restart Processes. Open the Task Manager (CTRL+SHIFT+ESCAPE).
- Update Drivers.
- Scan for Malware.
- Power Options.
- Find Specific Guidance Online.
- Reinstalling Windows.
How can you see what is causing the load?
To find what’s causing high load you can check few things.
- vmstat -w will show you ovierwiem (processes, swap, mem, cpu, io, system)
- pmstat -P ALL will provide you statistics (with %iowait) per cpu core.
- iostat -x look for high %util or long await or big average queue size.
What is high load on a server?
High server load is an issue that can affect any website. Some symptoms of high server load include: slow performance, site errors, and sometimes even site down responses. Troubleshooting high server load requires SSH access to the server where your site resides.
How do I find the server load?
Check the System Load on Linux
- Uptime. Check the load on your server using the uptime command.
- top. The top command displays real-time information regarding the server’s resource usage.
- free. The free command displays information about the server’s memory usage.
- vmstat.
- Summary.
How do you know if a load average is high?
If the 1 minute average is higher than the 5 or 15 minute averages, then load is increasing. If the 1 minute average is lower than the 5 or 15 minute averages, then load is decreasing. If they are higher than your CPU count, then you might have a performance problem (it depends).
What is high load average?
High load average sometimes implies CPU is overloaded with too many processes. However, this can be a different case depending on how many CPU cores are installed. One single CPU core can only handle one task at a time. The more cores system has, the more tasks system can handle in parallel.
How do you troubleshoot system performance issue?
Resolve any conflicts before rebooting your computer.
- Turn off your system.
- Make sure the hardware is properly seated.
- Check any cables that connect to the device to make sure they are secure.
- If PC Doctor is installed on your computer, it can scan and detect problems with hardware.

- GPU-Z.
- MSI Afterburner.
- HWiNFO64.
- Prime95.

How to troubleshoot high load with no obvious effect?
Closed 7 years ago. I’m running Ubuntu 13.10 on a laptop. Recently, after waking from sleep, I noticed the computer was quite warm, checked top and discovered 1.00 load average. I shutdown Chrome, various daemons, no effect.
How can I tell if my server load is high?
If you’ve used the above steps to identify high CPU load on your server, it’s time to find out why the load is high. The best place to start is again, htop. Look in the output below the number of cores and load average. This will show you the processes on your server, sorted by the percentage of CPU they’re using.
Who is responsible for troubleshooting high server loads?
Given that the range of causes are not specified within the error itself, a degree of investigation is required. Generally speaking, this investigation will need to be done by the server owner, their system administrator, or the server provider due to the necessary level of access that may be required.
Why is my Linux server loading so high?
The answer to that is “It depends.” You see, a lot of different things can cause load to be high, each of which affects performance differently. One server might have a load of 50 and still be pretty responsive, while another server might have a load of 10 and take forever to log in to.
