  • dotfiles and system configuration are pretty different use-cases, usually when you do system-wide stuff you want to manage not just the configuration files but also what software is installed and a bunch of other things. Ansible or something else like it is definitely the right tool for the job. And Ansible isn’t so difficult to learn, you only need to know like 5% of what it can do to be very effective.

    For dotfiles my personal preference is dotbot, but there are MANY many different tools that are all good and are just different ways to accomplish roughly the same thing.

















  • 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.
