Fix VMWare ESXi 6.* slow disk performance on HP b120i controller

I have been using the HP ProLiant ML310e gen8, as well as the HP MicroServer gen8 servers, fairly extensively. It was always working fine until I started using ESXi 6 and 6.5 on it.

MySQL command-line cheat sheet

As we all know, the hallmark of a good technician is the balance between laziness and productivity, where the important thing to note is that we are usually only productive about something that we want to be lazy about.
