Subject: Save memory option save little memory
Hi. I played with the --save-memory option and see a very little memory save:
jumbo version
john-1.7.9-j5 123MB cracking 1 million NTLM
john-1.7.9-j5(--save-memory=1) 114MB cracking 1 million NTLM
john-1.7.9-j5(--save-memory=2) 110MB cracking 1 million NTLM
john-1.7.9-j5(--save-memory=3) 108MB cracking 1 million NTLM
non-jumbo
john-1.7.9 64MB cracking 1 million LM
john-1.7.9(--save-memory=1) 52MB cracking 1 million LM
john-1.7.9(--save-memory=2) 48.7MB cracking 1 million LM
john-1.7.9(--save-memory=3) 45.5MB cracking 1 million LM
My system is Windows 7 Ultimate SP1 32 bits, Pentium M CPU, 2GB RAM.
--save-memory=1 result was expected as the username was very short but
for option --save-memory=3 i was expecting at least a half use of
memory.
saludos,
