Warm Greetings To GTALUG,
FYI.
Below is a forward of an email from one of the
developers of the DragonFlyBSD (dfly) operating system.
The PDF at the link target gives a nice one-page
graph showing the performance hits due to fixes for Meltdown and
Spectre.
Dfly is not LInux but a highly performant BSD
flavour I have installed dfly for testing under a VPS. Thinking to
use dfly, instead of Linux, for better HTTP server resource efficiency. But
also always keeping the website operational under a debian Linux for
development, reference, maintenance and emergency fallback.

Enjoy:

Meltdown+spectre
means that performance is dropped by 35%, and 99th
percentile of latency is
increased by 55%!
Thanks,
