Yes, I am seeing something similar on 0.4.8.9 (and potentially earlier versions as well, not 100% sure when it started). I upgraded to 0.4.8.10 today hoping it would go away, but I'm seeing it again. Watching in nyx (screenshot of bandwidth graph attached), reliably every ~30 seconds, I see the bandwidth briefly plummet and the tor process CPU spike. Guard relay running in docker under ubuntu server on a Ryzen 3600 machine with 32GB RAM. Note that when the relay restarted after the upgrade today, it didn't do this for a while (maybe an hour or so? wasn't watching it the whole time), but then started glitching every 30s. Once it starts it does this every ~30 seconds forever. Relay has been running like this for weeks, maybe months.
Yeah, on a more powerful host it crashes from 650 Mbit to 400 Mbit for a couple of seconds, on a clockwork-like regular schedule like you described. Hard to imagine devs would not have any idea what could cause specifically this.
I am retiring my relays as soon as 0.4.7 is banned (due to a number of other reasons as well, though).
