You aren't listening. The symmetric crypto is not the bottleneck:
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes
rc4 72846.67k 82979.15k 87698.53k 91231.05k 88004.03k
hmac(md5) 2272.39k 8280.19k 28745.41k 71355.13k 120523.95k
See: the per-packet MAC is an order of magnitude slower than the symmetric crypto.
The MAC is always included, even with Cipher=none.
There is no point in supporting Cipher=none if all you are doing is introducing
new risks without improving performance.
