Hello List,
Having been a happy linux-vserver user for more than 10 years now, it
was about time to test the hashify feature. The disk savings are
obvious, and easily measured, but I have been trying a lot harder to
measure any possible run-time memory savings. For the testing, I created
a simple template LAMP guest, and a lot of hashified guests cloned from
that one. I am unable to measure noticeably less memory usage when
running multiple hashified guests compared to non-hashified ones using
free and /proc/meminfo/'s MemAvailable entry.
However, this could very well be to shortcomings in my own understanding
how this should work or what to look for.
What should I look for regarding possible memory savings? Anyone with
any pointers?
This is Gentoo, util-vserver 0.30.216_pre3120, kernel Linux amd64
3.18.7-vs2.3.7.4.
