Yes, but that isn't really the point. Legacy and embedded computers without AES instructions don't get those gains, so they use blowfish. And those with blowfish configured will either A) fail to connect entirely due to "Ciphers: blowfish-cbc" excluding all others, or B) fall back to another cipher that's slow on that system. Things are going to break, is my point.

AES is slower for bulk encryption than Blowfish on old CPUs (at least those with enough data cache for the Blowfish tables).
