ASIO drivers consumes too much CPU

[DSBhproject]

Hi there, I'm on Win11, latest nightly build. I've noticed since the ASIO implementation in plugdata, it consumes too much resources and it happens on both the generic ASIO4ALL v2 drivers and the dedicated ASIO drivers of my sound card. It is not a huge difference but considerable (about 20% more than it should I think). In pd-vanilla, some projects works well and in plugdata I have to increase the buffer a huge amount to avoid clicks and glitches.

I suppose that due to the nature of GUI of plugdata, it'd be normal to consume a bit more resources than vanilla but this is too much, or not?

I can't reproduce that here with ASIO4ALL: both the task manager and the CPU meter at the bottom report only around 2% CPU usage. Where do you see the high CPU usage number?

Hi there,
Just to clarify, the high CPU usage and glitches (pops, clicks) in plugdata only appear when working with large, complex patches - patches that run smoothly in pd-vanilla but not in plugdata with the same buffer settings.
Thinking about it again, could this be related to the fact that Plugdata consumes more resources than Pd-vanilla? I suppose there is a difference — what I'm not sure of is that the difference seems so significant.

@DSBhproject What happens, when you increase block size?
And what's your computer specs otherwise, RAM/CPU, and DAW name and version?

If I increase blocksize obviously thing get a bit better in term of perfomance but more latency too. Sometimes I use plugdata with Reason but mainly this happens with plugdata directly as standalone app. I think the differences in CPU usage maybe comes from the fact that plugdata i a bit more heavy than pd-vanilla.
