Subject: Re: Parallella: bcrypt

Hello,

I tested the performance of bcrypt on one Epiphany core. These are the
results:

SIZE-OPTIMIZED bcrypt implementation compiled with -O1
    Message from eCore 0x88a ( 2, 2): Result:
"$2a$05$CCCCCCCCCCCCCCCCCCCCC.E5YPO9kmyuRGyh0XouQYb4YMJKvyOeW"#
    Execution time - Epiphany: 50.024000 ms

SIZE-OPTIMIZED bcrypt implementation compiled without -O1
    Message from eCore 0x88a ( 2, 2): Result:
"$2a$05$CCCCCCCCCCCCCCCCCCCCC.E5YPO9kmyuRGyh0XouQYb4YMJKvyOeW"#
    Execution time - Epiphany: 111.164000 ms

ORIGINAL bcrypt implementation compiled with -O1
    Message from eCore 0x88a ( 2, 2): Result:
"$2a$05$CCCCCCCCCCCCCCCCCCCCC.E5YPO9kmyuRGyh0XouQYb4YMJKvyOeW"#
    Execution time - Epiphany: 47.794000 ms

ORIGINAL bcrypt implementation using legacy.ldf
    Message from eCore 0x88a ( 2, 2): Result:
"$2a$05$CCCCCCCCCCCCCCCCCCCCC.E5YPO9kmyuRGyh0XouQYb4YMJKvyOeW"#
    Execution time - Epiphany: 40921.396000 ms

Size-optimized -

Original - www.openwall.com/crypt/

I also ran the runtime self-test and it returned correct result.
