UnOfficial Shelley Cconfig

Introduction

This is a not official recommendations for Linux based pool nodes. This, is my node's config which runs on Ubuntu 18.04.3 LTS (Bionic Beaver) server (/w Jormungandr v0.8.4) and does not have any issues at all, since the changes.

Before the change of the settings to these below, my node was struggling and missed almost all of the leaders' time due to the forks that caused by not having the latest tip/blocks.

After, I changed the settings, I have not missed any schedule for creating blocks.
