The Great British Sewing Bee (BBC). Even if you are not at all interested in sewing clothes. It’s so fucking wholesome and adorable that it’s a massive antidote to all the bad things out there. First season is still a bit rough, it gets better and better after that (there are 11 seasons in total now).
You’re probably correct, although I have no experience with zram so can’t be sure. But you’re absolutely right that PostgreSQL depends heavily on the OS disk cache for optimal performance. Lowering the PostgreSQL setting like Blaster M suggests won’t improve performance much, since all that setting does is tell PostgreSQL’s algorithms how much memory is likely to be allocated to the OS disk cache. Of course it’s best if it’s accurate, so you’re best off seeing how much memory is actually allocated to disk cache under heavy use before setting it, but it shouldn’t massively reduce performance if you don’t get it right.
