That is nice speed-up compared to generic hardware but everyone probably wants to know how much slower it is than performing same operations on plain text data? I am sure 50% penalty is acceptable, 95% is probably not.
- corysama 7mo agoThere are applications that are currently doing this without hardware support and accepting much worse than 95% performance loss to do so. This hardware won’t make the technique attractive for ALL computation. But, it could dramatically increase the range of applications.
- bobbiechen 7mo agoAgreed. When I was working on TEEs/confidential computing, just about everyone agreed that FHE was conceptually attractive (trust the math instead of trusting a hardware vendor) but the overhead of FHE was so insanely high. Think 1000x slowdowns turning your hour-long batch job into something that takes over a month to run instead.

- Foobar8568 7mo agoIt's Microsoft who did the library, damn, I can't understand how I misremembered that after working on it for a few months last year.
