Ugh, the hubris of n00bs.

I'm looking at tuning a #discourse server for performance, and I come across a thread. A senior guy who has migrated zillions of servers and runs a business hosting Discourse, counsels a person asking about tuning. The asker started by being worried about no available RAM. He had 8 unicorn workers (7 idle). He freed up some RAM by running fewer Unicorn workers and is happy that he has a couple gigs of free RAM.

The guy running the hosting company points out that making a bunch of RAM available is kind of a waste, since you're paying for it but not using it.

The n00b's reply? Available RAM is a good thing. His source? man free(1).

My dude. You think quoting a man page is going to school the guy who does this for a living?

🤦‍♂️
