LSP PEQ-16-stereo high cpu usage in headless mode [Solved}

[sunrat]

Following a suggestion in another topic using LSP PEQ for room correction, I tried it in headless mode with -hl option and have found it uses 25% of total CPU or nearly 100% of one core on 4 core i5 6500. Standard mode with GUI minimised uses 1% or less. Before I open an issue on Github, is anyone else using it headless and do you have similar issue?

pidstat output - Headless:

Code: Select all

# Time        UID       PID    %usr %system  %guest   %wait    %CPU   CPU  minflt/s  majflt/s     VSZ     RSS   %MEM threads   fd-nr  Command

With GUI:

What version of LSP Plugins do you use?

There was a related issue, and in current 1.2.5 version I don't see such behaviour:

Thanks @sadko4u . You can call me a dumbarse as I know better than to report an issue with an older version than current. I thought I had updated but still had an older version (I ain't saying how old )
v1.2.5 is working beautifully.

Code: Select all

Average:      UID       PID    %usr %system  %guest   %wait    %CPU   CPU  Command
Average:     1000   3467884    0.30    0.07    0.00    0.03    0.37     -  lsp-plugins-par

Also the GUI version reports much less CPU usage than the older one when GUI is visible.
