Hi!

I present some interesting numbers regarding startup times and memory footprints. This started as a simple list but grew and expanded as raster pushed me along. I really only needed a little bit of data for my Uni assignment to put in a CSS table. It’s now a fairly comprehensive test. These results come from my system, with a slight bit of tweaking to make all the environments used to my liking, yet quite minimal. Results obviously vary from system to system and this is the raw results I found on my system. Your results may differ. (Now with shiny graphs!)

*** Each environment was slightly tweaked to make it

more user friendly and usable. They are all very close

to being a default setup. GDM auto-login was used.
