| Summary | 0010061: Ardour 9 seems to be using more CPU | ||||
| Description | With a project "idling" (not playing, not recording) in 8.12, the DSP is typically 11%. Repeating with the same project in 9, the DSP is 31%. This is with my CPU in powersave mode. If I change to performance mode, the figures become 4% and 11% typically. I've put this as minor severity but I don't think it's for me to say really! | ||||

Do you use an optimized build of Ardour 9 to compare? (check menu > help > about) (debug builds also introduce overhead in DSP) |
|
|
I can't see anything about optimized but 9 is def. a debug build whereas 8.12 doesn't mention debug. So presumably that's the explanation. |
|
|
Why don't you test and compare with Standard non-debug Ardour 9.0 rc1....? |
|
|
With optimized / non-debug 9 rc2, the DSP is back to what it is with 8.12. |

Not a problem, no issue |
