How to debug lag using Bluetooth connected mouse and A2DP headset?

I have just migrate to 12.10 and I have noticed that I have huge problem with my Bluetooth mouse left click button on a high load (wired, but scroll and right button are not affected). I think powersave cpu mode affect that more than cpu load. It just not "trigger the interrupt".

Mouse is laggy, click are not registered. I cannot work like that. At the same time, my touchpad and usb mouse works great.

How do I check the - limit cpu frequency (I use powersave and ondemend mode)?

I now wonder, what should I log, check, measure, to capture enough data to fill bug report.

Any suggestions?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

At the moment, I've changed cpu mode: powersave -> ondemend (mouse working ok) -> powersave (mouse still working well) so I'm a bit confused...
