[GTALUG] Fw: Meltdown and Spectre on HTTP workload

[Steve Petrie, P.Eng.]

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.

Steve

Enjoy:

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

Thanks,
