Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: puredata Group: None Status: Open Resolution: None Priority: 8 Private: No Submitted By: Piotr Majdak (piotrmajdak) Assigned to: Nobody/Anonymous (nobody) Summary: Higher CPU load in 0.39 than older versions

Initial Comment: Updating to 0.39 I noticed that most patches use more CPU than in previous versions. Configuration: OS: Windows 2000, ASIO driver activated.

CPU Load without any patch loaded: - 0.38.3: 2% - 0.39: 4%

CPU Load with a patch: - 0.38.3: 3% - 0.39: 40% (!)

CPU Load with comport object receiving data from serial port: - 0.38.3: 3% - 0.39: 25%

It seems to depend on audio channels used: more channels higher CPU load. It is hardware independent (several sound interfaces tested with different computers).

Two years ago, we stopped using 0.39 because of this bug and we adapted our patches to 0.38.4-extended which works fine. Unfortunately, I can not contribute to this issue at the moment because of lack of time. Sorry...

An example patch is always very helpful, especially if it triggers the problem every time that it is run. Ideally the example patch would have only enough objects to cause the problem, but nothing else.

does this still happen with the 0.40 prereleases? if so, could you narrow down the problem a bit?

changed priority: this bug makes 0.39 unusable :-(
