Title: High CPU Usage [Solved]
Post by: Talisker69 on November 21, 2018, 03:52:23 am

Hi Every Body,
I'm testing JRiver before buy it because i want to use it for room correction (convolution).
I'm running Linux Mint 19 (Cinnamon) with the last version of MC 24 (64 Bits) and the last stable kernel on a NUC 7i7.
I'm surprising by the CPU usage, even i'm not playing anything and stop the DLNA server, MC consume 94% on one thread !!! Is it normal behavior or do i make some changes ?
Thanks in advance

Try disabling the spectrum analyzer (right click where MC displays song information in the main MC window, and uncheck Show Spectrum Analyzer) and see if that helps.

It also might be thumbnailing, you could drop the priority and see if that helps.

Or Audio Analysis.

Ok thanks, it works better now; I don't really know what's happening but now the cpu usage is correct (around 10%)

10% still sounds too high to me for an i7, or is cpu use on the linux version that much higher? With 6 year old i5s, I see total cpu around 6% with mac 10.9 and windows 10 64bit and playing wav redbook 16/44 files with some dsp.

Was this while playing redbook flac or wav? As others stated, those things will run cpu up a lot more until they finish updating your library.

Its important to note that tools like htop as shown in the OP report CPU usage differently as one might know it from Windows. If it reports 100% use, thats 100% of one core - on a quad-core on Windows that would be 25%.
10% usage of one core during playback or some other background activity sounds normal for me.
