Snaps use a compressed disk image, which is uncompressed and mounted the first time the process is run after startup. All of them are slower on first startup than their non-snap counterparts. And unmounting these during shutdown can cause the shutdown to take a minute longer than expected. That may have been a bug that was fixed since I found out about it, though.
