So far the main CPU hog is (unsurprisingly) media encoding, especially video. Luckily this occurs off the main thread, inside C function calls. Unless I'm mistaken the GIL is released, so there is no Python-specific downside on this specific point.
I've found heavy usage of asyncio.Queue to bridge consumers / producers does not lead to amazing performance, so I'm trying to cut down on that pattern in favour of.. callbacks (I know - not very asyncio-ish). A good testcase for testing performance without media encoding is transferring large amounts of data over datachannels (see datachannel-filexfer example). I usually hit ~ 70Mbps on the loopback interface, which is more than I've managed to get out of browsers.
I can't say I have experience with using aiortc at scale yet, so there are almost certainly so hotspots I haven't seen.
