In the previous blog post we have seen how plenty of ram doesn’t necessary results in a faster instance.

This time we’ll quickly see how PostgreSQL and Linux relate to each other in particular if we want to run our RDBMS at scale.

Then we’ll have a look to the virtual memory in Linux and how to make it more friendly to PostgreSQL.

When I first read about the systemd I truly believed the linux community would be able to improve this init system. Or at least to stop it if not good enough to be used as replacement for sysvinit. I was wrong. After a strong and poisonous debating Debian switched to systemd in Jessie. Several contributors left Debian and organised a fork called Devuan which is pushing for the init freedom.
