I did notice when using A3, CPU usage was up to 40%. But when using A2 with the same session, it was 5%
During Playback A3 CPU usage would boost to 60-70% where in A2 it was at 10-15%

As shown in the attached screen shot. I noticed today that the CPU usage was oscillating from 10-20% for 15 seconds to 40-50% for 15 seconds. This only happens when A3 is at idle. During playback and recording, it jumps to 50-60% for 15 seconds to 80-100% for 15 seconds.

How many cores have you told Ardour to use? (Edit -> Preferences)

Do the xruns happen when DSP usage changes? Could be related to frequency scaling.

check

cat /sys/devices/system/cpu/cpu?/cpufreq/scaling_governor

Setting the number of cores to 2 when you only have 2 might cause scheduling problems. Do you still have the problem if you tell Ardour to use "all but one processor"?

 I tried the "All but one processor" and 1 with worse performance Before it was xruns only during playback and recording. With only one or all but one, I get loads of xruns at idle.

I tried "All available" but it was the same results as if it was set to 2.

Attached is another screen cap of the system monitor while using all but one.

Just updated to 3.2 and just changed out my video card. Still having issues. One thing to note but might be irrelevant; When loading a session, the first few xruns start when the Ardour splash screens says "Rest Remote Controls"
