Sawfish still lightweight?
Correct me if I'm wrong, but can Sawfish still really be considered a lightweight window manager? I know it started out as being "more lightweight than enlightenment with better Gnome integration and configurability", thus giving it its popularity, but I doubt it still can be considered to be lightweight.
Feature creep, own rendering engine and running interpreted code must clearly make it much heavier than for example Metacity, IceWM and BlackBox.
I remember seeing a more detailed comparison where a modern version was shown to be many times heavier than the ones I mentioned (at least 3-4 times!) and even heavier than enlightenment, but I haven't managed to find it again since then.
Of course, certain factors always play in like what theme is being used and what other programs are being run (Metacity might for example take up more resources than many other window managers if it's the only GTK2 application in use since the weight of the toolkit then must be entirely attributed to Metacity).
Please correct me if I'm wrong or add some details if you have more information.
Doesn't lock display and runs nicely in background now...
Comment about bladeenc locking the display is only valid for very old versions of BladeEnc. BladeEnc now runs nicely in the background as well if you use the -quiet switch or change the progress indicator (-progress=[1-8]) and redirect output to a file in order to supress terminal output.
