19:43:51 <UkoeHB> I added a perf test for view key scanning: https://github.com/UkoeHB/monero/blob/seraphis_perf/tests/performance_tests/view_scan.h. It compares seraphis scanning (with and without view tags) with cryptonote scanning (without view tags). As I expected (https://github.com/monero-project/research-lab/issues/73#issuecomment-634961245), seraphis scanning with view tags is 25% faster than cn scanning without view tags (the same crypto 
19:43:51 <UkoeHB> ops are used up to the view tag branch). Seraphis without view tags is slower since I did not optimize the post-tag branch (why bother? :) ).
19:43:51 <UkoeHB> I also added a test for cryptonote view key scanning with the basic `crypto` library vs `supercop` (I think?). The supercop library calls seem to be 50% faster.
20:00:27 <selsta> Can Seraphis also use supercop to speed up ecc crypto?
20:01:06 <selsta> ec crypto* :)
20:04:57 <UkoeHB> maybe? idk how to use it
20:15:20 <selsta> UkoeHB: two wallet functions are implemented here https://github.com/monero-project/supercop/pull/3/files
20:16:30 <selsta> see basically src/amd64/amd64.c.inc
20:16:33 <selsta> but I guess that's not important now
20:16:52 <selsta> I don't see why it wouldn't work with Seraphis
20:18:12 <midipoet>  stupid question, but what's a view tag?
20:20:12 <UkoeHB> midipoet: https://github.com/monero-project/research-lab/issues/73
20:26:28 <midipoet> thank you
20:35:16 <UkoeHB> selsta: nice, I was able to easily reuse the `generate_key_derivation()` method for seraphis
