Well, the goal is to read it by yourself - for each failed steps it gives you hints on how to fix it (might need to be adapted for your distro).
the main issues are apparently:
- cpu governor is set powersave and not performance -> fix that first
(think about a WV engine passing an emissions tests vs full throttle on the German highway).
you can try “sudo cpupower frequency-set -g performance”
- no rt kernel (either because the ccrma low latency kernel doesn’t have the rt patch or because you didn’t boot from it).
Better have it, but it is not as bad as it used to be. You don’t necessarily need an rt kernel those days - that becomes really useful for sub 5ms latencies.
The rest is either for midi or minor.
Your soundcard is on irq19, but I don’t think there’s an issue at this stage, like the rt kernel, you shouldn’t need to worry much about rtirq at 16ms latency.
Missing from the quickscan output is also the limits.conf settings - this one is important
Be careful, there are 2 possible locations - this is distro dependant:
/etc/security/limits.conf or /etc/security/limits.d/audio.conf
Once set (needs a reboot), verify that Renoise is running at a higher priority (should be around 90 if you followed the tutorial to the letter - you can go up to 99).

Regarding the CPU: as Fernando said, don’t touch if you don’t know what you’re doing.
I wouldn’t recommend to disable hyperthreading (at least yet). Reason: HT works relatively ok on modern Intel Core cpus - that was not always the case.
But you may want to disable turbo boost. Reason: setting your cpu to performance mode might push the thermal enveloppe to its limits.
If the fans go to the roof but the cpu cannot maintain a stable max frequency, disable it. If it’s a desktop with a big cooler that might not be needed - you judge.
If you didn’t run to buy a mac yet, you might get better perf already - good luck
