I understand that cpu usage when using daws are not measured by cpu meters as they are measured by the buffer size etc, if I used a buffer of 8192, wouldn’t I get more performance from my cpu since it will give the cpu more time to process the audio, also wouldn’t I be able to neatly maximize the cpu cores when running a session, I don’t know if any buffer sizes above 8192 but I assume if there was I would actually be able to hit maybe almost 100 percent cpu usage if I am using it heavy particularly in large sessions for film, tv etc. There’s times where dsp usage gets high but cpu meter is nowhere near 100 percent but I just change buffer settings and I’m good to go. Also does using high buffer settings cause any lag or reduce percentage in plugin guis or meters
Ok a little difficult to follow your question, but I tihnk the answers are:
-
Yes higher buffer size will allow you to process more, and allow for more work to be done by the CPU as it has a longer window of time.
-
A faster CPU will still improve things, even though the DSP measurement from Ardour is not just processing but also a window of time, the faster cpu will process more in the same window, at least in theory
-
Yes increasing buffer size increases latency. But really this only comes into play if you are live processing audio or playing a MIDI instrument as the latency is accounted for in recording.
-
Increased Buffersize and Meters… well I would think that would depend on the plugin code in question, theoretically it shouldn’t make a difference I would think.

Oh ok, I was told that certain buffer settings causes things to slow down but I don’t think that’s the case.
Smaller buffer size = the less time the CPU has to process the audio = the slower your system runs (because the CPU is running harder).
In theory, there are maximums to your buffer size for certain sound cards. Mine is 2048 with a Behringer UMC404HD.
There are no buffer sizes that JACK supports above 8192 but that’s like 30ms of delay or more I believe.
Oh ok good to know, I have noticed as well certain sound cards support certain buffer sizes
