I read this article of the weekend which was reporting that the latest
Linux kernel kills postgresql performance:
https://www.phoronix.com/news/Linux-7.0-AWS-PostgreSQL-Drop

I haven't seen any discussion here about this yet and was wondering what
your thoughts are? Are we doing to have to upgrade our postgresql versions
before we can upgrade our Linux kernel? Are there any hacks or tricks or
workarounds to help mitigate this issue?

Is it real?
