MODERATORS
Doesn't really seem like news to me, encryption makes communication slower, that's pretty standard.
Sure, but 20-40% slower? That points to something being poorly optimised.
Yes, that's what happens when there's no hardware acceleration and it fails back to software.
They should still be using the CPU's built-in AES hardware acceleration, yes? It seems they have good reason not to trust the SSD to handle the encryption but that doesn't mean it has to be entirely implemented in software. CPU-accelerated AES shouldn't be that much slower.
