Build from source 100x slower than prod

[thaas]

Apologies on the delay here, but here are the two outputs:

First, from the website:

Code:

hashcat (v6.1.1) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

Kernel /usr/local/share/hashcat/OpenCL/m08900-optimized.cl:
Optimized kernel requested but not needed - falling back to pure kernel

Both were run with "hashcat -b -m 8900"
