An SSD can make a world of difference. Most of the time spent during boot up is in executing random reads (of about 4Kb size) from storage, and SSDs are a factor of magnitude faster there
POST time is crazy bad. It's almost like the engineers working on it don't care.
Maybe I've just gotten really lucky...
Not implying that it's bad software, I'm just curious because it sounds unusual.
The example I gave above happens regularly, as I use Deepin Linux as my typical daily driver while I'm working. However, if the need to open an adobe suite tool comes up, I can quickly swap over. Discord works fine for me on both platforms and my phone.
All in all, I don't really like discord all that much. It's not the best at anything. But it has the advantage of being both convenient and feature-rich overall. There are better solutions out there, but none are as convenient or free.
