I am a heavy VMware workstation 10.0.3 user, and as such I have 32GB RAM on my system. My only operating system is Arch Linux, using Unity for the desktop.
Usually when I have two virtual machines running with about 3GB RAM appointed to each, really often and at random intervals the whole system becomes unresponsive for a few seconds.
Running "top" at a terminal, the culprit seems to be the command khugepaged, which runs while the system is unresponsive at 100% CPU and then dissapears.
Is there any way to avoid this? I have googled about khugepaged, but I only seem to find ancient posts from 2011 or unanswered questions.
These are my full system specs:
- CPU: Intel i5 4570@3.2GHz
- 32GB Corsair Vengeance RAM@2400MHz
- M/B ASrock Z87 Pro 4

I have similar problem on Ubuntu. The workaround I use is:
The source of the workaround is in a Fedora bug report “khugepaged eating 100%CPU”. The bug was never fixed.
This is less drastic then disabling entire
transparent_hugepage
support. The detailed explanation of what the command does can be found in the documentation of transparent hugepage support.
