CPU load

[ah1102]

When receiving one channel AM, a processor is loaded by 120%. All four cores of the CPU. Even the absence of any listening loads the CPU to 100%. The program's CPU usage indicator bar is always full and never goes down. Is this normal? Is this the case for everyone, or is my processor already very outdated?

OS: macOS BigSur
CPU: Quad Core 2.7 GHz Intel "Core i5" I5-3330S (Ivy Bridge) processor
RAM: 1600 MHz DDR3 SDRAM

I have a MacMini (Late 2014) that has a Dual Core i5 @ 1.4 GHz with 4 Gig of ram and I am on a P25 system. CPU load is about half at idle, no audio traffic, but when a call comes through it goes to full bar.

Very outdated CPU. Nothing but headaches in your future. Try something else if you serious about using SDRTrunk. I'd personally even skip the PI's and low-end miniPC's. I wouldn't go less then 6-8 cores/16gm ram for my SDRTrunk setups. Laptops are fine but use a powered USB hub. [https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-3330S+%40+2.70GHz&id=1794]
