Hi,
Thanks for the replies. I'll forward my query to the Logic forum.
The AU's performance seems fine under Ableton Live, AULab, Bias Peak, and
Garage Band. The performance problem only seems to be in Logic.

Can you also try your AU in AULab - what is the performance like there?

Paul,
This might be better addressed to the logic team. It's hard to speculate
as to why you would get less performance under logic. Please post your
message on the logic forum.

Hope this helps,

Hi,
I'm not sure if this is the correct mailing list for this, so please
forgive me if it isn't.
I have an AU which is fairly graphically intensive (its a metering
plug-in). It seems to perform reasonably well under Ableton Live, but
under Logic, it is jerky and unresponsive. To try to investigate I have
added some profiling code to log out the number of times a function is
called in each 10 second period, and how much time was spent in that
function.
I found that the most time-consuming functions were my more elaborate
graphical display functions, which wasn't a surprise, but strangely I
found that under Ableton, these functions were hit more often, but took
less time than they did under Logic. The gui of my AU is built using
vstgui.
It seems as if the graphical performance of my plug is very dependant on
what AU host it's running under, but I don't know what could cause this.
Thanks for any help.
Paul
