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.

It is not that bad these days, closer to 10,000x.

Accelerators are being developed that claim to get down to 10x, though i think they will be more like 100-1000x, which would still be a huge improvement considering how people use LLMs today for basic tasks like string matching.

Are those accelerators software-only? 10x could let 4$ VPS run server side checks for backup software (evil clients cant clean backups) and git forges (eg, dont allow X to push to main).
