If you run VMware Workstation 11 or above you may encounter high CPU usage from process khugepaged on Ubuntu 15.04+
The fix is to disable transparent hugepages. It seems Ubuntu has it enabled by default.
You can check the current status on your system by running:
always [madvise] never but Ubuntu outputs:
[always] madvise never
Fedora seems to not be effected but I havn't tested it myself.
So I suggest not using madvise and just disable it totally.
To disable it run the following commands as root:
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
That will only disable it for the current session.
To have it persistant across reboots I suggest adding this to your rc.local:
# Fix for VMware Workstation 11+ khugepaged. echo never > /sys/kernel/mm/transparent_hugepage/enabled echo never > /sys/kernel/mm/transparent_hugepage/defrag
Ensure this goes above the line:
