>> Performance monitoring data shows increased pressure on the decoder in SMT mode across all integer workloads.<p>That's probably why AMD put 2 decoders in Zen5.
One thing I'd be interested in, which kind of belongs in this space:<p>In the last years, there were lots of performance reducing software patches for security flaws in CPUs, e.g. meltdown, specter and god knows what. Is there a way to disable those security fixes and increase performance, e.g. for servers that only ever run self written backend code and if so, is it common practice?<p>I feel like I wouldn't want those security fixes on that server I am running which only runs postgres, is only accessible to other servers via the postgres port and does nothing else.
