Ubuntu 12.04 flush-encryptfs resource hog

rated 0 times [ 0] [ 0] / answers: 1 / hits: 673 / 3 Years ago, sun, may 30, 2021, 10:45:06

I've been using Ubuntu 11.10 for a while, but recently upgraded to a fresh install of 12.04 LTS.
I am noticing a program called flush-encryptfs- using a significant portion (30 to 80%) cpu resources. It seems to start running when I launch chrome. If I close chrome, it will eventually stop. This is having a huge impact on system performance.

What is flush-encryptfs-? What is it doing? How can I stop it?

I am using an Asus Eee PC netbook. It's a new install of 12.04 with very few additional programs installed and yes I encrypted my home folder.

I think you mean 'ecryptfs'. eCryptfs is a program for encrypting partitions and directories. Apparently encrypting your home folder takes quite some hit on your CPU performance.

I found it in general more useful to encrypt certain folders rather than the whole /home. /home contains a lot of configuration files that are accessed all the time by various programs, and each access makes ecryptfs work.

That said, I still find the CPU usage you report quite high.
