It’s at least a million times slower than non-encrypted computation. 1000x or 100x would be a huge progress.

Oh. It really is that bad still. So if the question is between wrapping the plaintext in layers of security, or building out a million new server instances to do it via FHE, i know which one everyone will choose.

		It's so bad that the only way FHE can get more efficient is to use a non-conventional compute technology. Some want to do it in optical donain.
