First, of course, don’t hold me responsible for what you do to your system — the responsibility is entirely yours.

There are several processing strategies that, despite producing a substantial performance gain, ended up introducing security flaws. What I did was take two machines from my cluster and configure the Linux kernel not to disable those features.

In my case, since I use Debian, I edited the file /etc/default/grub and added mitigations=off at the end of the GRUB_CMDLINE_LINUX_DEFAULT variable.
