Title: High CPU usage
Post by: kobber on August 31, 2026, 05:56:17 PM
Hello. I'm using wacap + ignorant output + streaming DSP plugin + icecast server on the same computer. That's work fine, but after a couple of days CPU's consumption is about 15% from 1% at the start moment.
If I started two portable wacaps to stream two different playlists, each of them eats 15%, total is a 30, and laptop started a cpu cooling fan, so noisy.
Playlist is about half-thousand mp3+flac files, shuffled.
Is there any thoughts how to log this problem and fix it?

What wacup version & build type, Windows version & what skin are you using? Additionally is the local library being used & which streaming source are you using (wacup's or a 3rd party). Also to confirm the stream renders ok when it's showing the problem?

The obvious thing would be to see if the 24960 build from earlier today shows any improvement or not. If not then trying to get a couple of process dumps whilst it's in that odd state via task manager & then send them over to me (they compress well but might need to hosted somewhere temporarily if a few have been generated).

It might also be possible to use something like process explorer to see if it's a single thread or if multiple threads in the process are running at full speed (not that the length of time should make a massive difference unless it's maybe not keeping up or it's not able to send it to the icecast instance as fast as wanted & is having to spin).

Thanx for the answer. I will update to last build and take a look at its behavior

Hello.

1. 24960 32-bit, win10 pro x64 22h2, classic skin
2. Yes, is used playlist with local mp3 and flac-files.
3. It uses Ignorant output and dsp_wc plugin with one streaming source to icecast server
streamig is working fine without gaps, lag etc, but cpu consumption has grown in 5 days to 13%

got some screenshots
