  • One is a Pinebook Pro, which is an RK3399 processor. Another is a Surface Go 2 with an Intel Pentium Gold Processor 4425Y.

    The actual issue is that the video conferencing works, but trying to do anything else is just suuuper slow. Well, the Surface Go 2 is actually fairly good as long as I’m not touching the ZRAM. But, trying to share a window in Google Meet will always involve a lot of waiting. Firefox and Chromium seem equivalent on the Surface, but the Pinebook seems better in Chromium lately.

    I can bare-bones most apps I use on these laptops, but for video conferencing it seems like I have to drag along a whole browser.



  • I’m surprised how many people turn their computers off. My desktop uptime is 4 day, but, I do put it to sleep at night (which I think counts towards its uptime).

    I will look into hibernating. The reason I don’t shut down is because I usually end up with carefully placed windows and lots of ongoing projects all over. Restarting would mean I’d have to start all that up again - assuming I remember what I was doing.


  • For whatever it’s worth - I have a laptop with 4GB of RAM and a 4GB ZRAM device, and it can’t use all the ZRAM before everything grinds to a halt. I think the way ZRAM works best is if it can “swap out” (compress) anonymous pages that aren’t actually needed again right away, freeing up the fast memory for disk caching and other memory needs.

    In my case, I think I can reach a point where the amount of memory Linux needs simultaneously active goes beyond the 4GB of RAM, so it’s just compressing/uncompressing forever and getting nowhere.

    So, I think I’d argue that maybe you can’t go too big? I think only anonymous pages can get compressed, and there’s probably only so many gigabytes of those in memory at any given time.
