Yes, OCB is still around 50 % faster than the next best[1] AEAD (which is AES-GCM) and almost 3x faster than Chapoly on current x86 and comes pretty close to 10 GB/s/core on a desktop CPU. That being said, all of these are really, really fast in absolute terms, way beyond line-rate even for 10 GbE, which is a measly 1.2 GB/s. In practical terms, all of these modern algorithms are so fast (with hardware support for AES) that very few applications will see a significant burden from symmetric crypto, so you can choose pretty much whatever you feel comfortable with. EtM was usually quite a bit worse, as the hashes used for hMac were usually much slower in comparison. Though Blake3 would seem to eliminate that concern.
