Show your LEB Memory usage. Are you Low End?

Raymii · August 2014

Just to compare how Low End everyone is.

Usage, as root:

 curl -sk https://raw.githubusercontent.com/pixelb/ps_mem/master/ps_mem.py | python

Or, clone this repo: https://github.com/pixelb/ps_mem and execute the ps_mem.py script with python2.

Output from my busyest low end box, it runs DirectAdmin and a few sites which family members and friends use and manage, it has 512 MB RAM:

We can have negative memory usage? Does that make sense?

serverian · August 2014

Using less memory doesn't make you special unfortunately. Using less CPU and IO = more caching = More memory makes you special. Memory is not even a bottleneck on the servers for the last few years.

serverian said: Using less CPU and IO = more caching = More memory makes you special

What about using less CPU, IO and RAM - does that make me special?

I suppose adding cat /proc/loadavg or uptime to the script would be nice, but meh, this is all just for interest sake anyway, not a general statement on efficiency.
