Benchmark testing - proving what LXDE can do.

[Chriswaterguy]

(This is more about publicity than development, but I couldn't find another forum to put it in.)

I've been spreading the word about LXDE (including through @appropedia and @chriswaterguy accounts, on Identi.ca and Twitter). Part of what I'm finding is that many Linux people aren't aware of what it's capable of - and of course there are so many claims about what is fast and what is light, that something more attention-grabbing is needed.

Can we arrange benchmark testing of the different desktops? This could attract a lot of interest among Linux users, and show what LXDE has to offer. Something like the fairly in-depth one described on kde.org (Jan 2007 or earlier, from looking at web.archive.org, but it doesn't include LXDE). Another example of benchmark testing (a very simple test of RAM usage, comparing XFCE and LXDE) is here (reply #9 and #10).

I'm not in a position to do this myself (I have one computer, which I need for work). But if anyone wants to do some benchmark testing, either simple or in-depth, please link or post the results here.

A really proper test would include at least Gnome, KDE, XFCE and LXDE. (Even more thorough would be to add Openbox, a Crunchbang-style implementation of Openbox, and JWM, which is the standard Puppy Linux desktop environment.) But even a simple test like the XFCE/LXDE comparison above is worth doing.

A big part of lightness on memory usage should be that in an LXDE system the distro doesn't start things that don't need to be running.

A comparison of taking, shall we say, a Gnome desktop, tearing out the Gnome panel, and starting LXPanel instead, without doing any other slimming, will be flawed for that reason.

I am working toward having the minimal set of overhead processes be: init, syslogd, klogd, udevd, dhclient, acpid, cupsd, ntpd, dbus-daemon, pulseaudio, display manager, Xorg, window manager, panel. With some of those, like ntpd, dhclient or pulseaudio, possibly not always wanted.

Agreed. I'm not sure why you mention it - I am not suggesting such a test.

What about my suggestion of comparing Gnome, KDE, XFCE and LXDE? It would need to be done on a distro where each of those desktops has been implemented reasonably well. Debian? Fedora? Mandriva? Not sure which. Then we could even compare Windows on the same machine, for a bit more provocation .

Seems like a very good idea to me, but it obviously hasn't caught the imagination of anyone else here. Ah well.

A lot depends on the distro used, for example Lubuntu starts more services and uses more ram than Lxde on a Debian system. Things like prelink/preload can also have an effect on how much ram is used and how fast apps start.
