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.

OCB isn't committing, so it doesn't solve the stated problem.
