22:29:22 <UkoeHB> I'm getting ~40% speedup on my machine using tevador's x25519 implementation for view tag scanning compared to cryptonote view tag scanning (i.e. 1) compute DH derivation, 2) compute view tag). A small amount of that is from using blake2b for view tags instead of keccak (<5%).
22:32:46 <selsta> plus it should allow significant speedup for mobile devices since they don't have any assembler optimized code currently
22:33:49 <xmrack[m]> very cool
22:34:18 <xmrack[m]> So what would the total speedup be using x25519 compared to no view tags?
22:34:52 <UkoeHB> not that much, since there are a bunch of steps after view tags
22:35:55 <UkoeHB> but the view tag filter handles 99.6% of enotes on-chain
23:58:16 <UkoeHB> oh you mean compared to pre-view tags? about 55% per enote on my machine
