That's how to do a comparison :) Clear and straight-forward explanation, results, and no time-wasting video. Well done.

- itvision 4y agoThanks. For those who are interested you can download the source images at the bottom of the article. People have been questioning applications/services/daemons running in background for each DE - you can check that.
- Adverblessly 4y agoOne thing that was missing for me was how you checked RAM usage, since a similar previous comparison that was posted on HN actually measured something different than what most people expected. Since you helpfully posted the source images I checked to see what you did :) I saw that you used the output of "free", which I think is not what most people think of as RAM usage (IIUC it reports the total virtual memory in use). I usually look at the output of `smem -atk` and look at total PSS. See https://lwn.net/Articles/230975/ https://lwn.net/Articles/230975/ for a clearer explanation on that.
- itvision 4y agoI completely flushed system buffers prior to getting the results (echo 3 > /proc/sys/vm/drop_caches), so the free RAM that I posted is indeed absolutely free yet it cannot be reused.
