    Method of comparing the RAM use of an OS?

    Any ideas of how to compare operating systems (mainly distros) memory consumption? Possibly with a view to creating a list of distros suitable for old machines on criteria of memory use (rather than compressed image size).
    Installing the distro (wouldn't work live, would it work virtualised?).
    Installing conky.
    Recording the result.

    make sure you always measure it the same way. If you use something like system monitor it isnt all that accurate especially if you use different programs on different OSes. Instead use the command
    Code:
    free -m
    Desktop: Q6600 OC: 343 x 9, 4 GB RAM, 8600 GTS Twinview (22",17"), 1.5 TB RAID 5
    Laptop: Lenovo T61 T7300 @ 2 GHz, 2GB RAM, Nvidia 140M Quadro, 160 GB harddrive

    You should also note CPU usage.
    I've noticed that many distros use less memory but more processing power.
    Symptoms are about the same.
