@IRJ As in, you shouldn't be scanning everything on the open internet.
The FBI, NSA and other 3 letter government agency's will come knocking down your door.
They have neither the resources nor the inclination to go after everyone that runs a simple scan. They don't in fact have the resources to go after all the people who have committed significantly damaging illegal acts let alone anything else.

I see about 10 scans a minute from all over the world on our external servers on a slow day!

Exactly and if US law cannot do anything then what are countries like China and Russia going to do? lol

Yeah I am sure China's focus is to find everyone running nmap scans on American servers so they can execute them.

No they wont. It's like walking or driving up to a house and looking and casing it out for a robbery. You aren't doing anything illegal until you breach the house.
actually this is now illegal in some country - not this exactly, but I can't recall where, some country (Japan maybe) just passed a law where it's illegal to plan something illegal.

Of course it is - it's just like another gun law - just one more thing to through at people after they are caught.
Like Capone and taxes.. -

It's illegal most places, but impossible to prove.

I have installed using the hyperv image on my workstation. Have run a scan.
The scan results don't make any sense.
It is showing I am running about 10 different insecure versions of linux kernel, none of which I am running on the machine I scanned.
Above is a snippet of a pdf report of the scan showing me a list of kernels which are not on this server as far as I know.
uname -r
returns
-
Running
rpm -qa | grep kernel
showed 5 or 6 kernels still installed. whoops.
package-cleanup --oldkernels --count=2removed all but the current and next oldest one. -
It's defiantly taking my cpu for a sprint.....

As mentioned in the OP, OV is very resource inefficient. Nessus is a night and day difference, but isn't cheap.

I've seen this before when credentials don't work and a vulnerability scanner has to guess the OS version. Are you sure the credentials worked on that first scan?

Nvm reading comprehension helps.. Lol

Another thing to note is that Credentialed scans are much more polite compared to non Credentialed scans. Non Credentialed scans are much more taxing on the box since everything is guessed slamming the box.

A non-credentialed scan would be more akin to a hacker attacking and trying to get in, I would think.
Have you tried throwing more CPU cores at OpenVAS instead of / in addition to RAM?
I ran it on 4GB RAM / 4 CPU Cores for ~30 Servers and got reasonable performance out of it.
