Subject: Re: Anyone want to benchmark AVX2 code for bcrypt
Windows 8 x64 4770k at 4.1GHz
Single threaded performance:
AVX2: 868.6 h/s
Hashcat: 1170 h/s (hashcat-cli64.exe -m 3200 -a 3 -n 1 m3200.txt -1 ?l?u?d?s ?1?1?1?1?1?1?1)
So not using AVX2 is faster. One reason might be that it runs out of L1 cache (needs more than 32.5 KiB but there's only 32 KiB of L1) and has to hit L2.

Run this http://www.tobtu.com/files/bcryptavx2.zip (the source is included along with a 32 bit Windows and a 64 bit Linux binaries).
The non-AVX2 code is a little slow. I was too lazy to interlace it. Anyway
if you also have numbers from JtR (--format=bf) or Hashcat (-m 3200).
It's doing $2y$05$...
