Drop performance md5 salted
#1
Hi there,

Configuration:
Ubuntu 10.10 64 bits
Forceware 280.x
Nvidia GTX 580 (3x)
ocl

I have a drop of performance when I try salted md5 hashes (-m 2) compared to md5 (-m 0):

Hash.Type....: MD5
Mode.Left....: Mask '?1?1?1' (238328)
Mode.Right...: Mask '?1?1?1' (238328)
Speed.GPU*...: 2581.4M/s

vs

Hash.Type....: md5($salt.$pass)
Mode.Left....: Mask '?1?1?1' (238328)
Mode.Right...: Mask '?1?1?1' (238328)
Speed.GPU*...: 35.9M/s

(./cudaHashcat64.bin -m 2 -d 1,2,3 -o /tmp/tmp --gpu-loops=1024 hashes -1 ?l?u?d ?1?1?1 ?1?1?1) on a list of 64 hashes.

Strange also that the % indicate:
HW.Monitor.#1: 0% GPU, 71c Temp
HW.Monitor.#2: 0% GPU, 70c Temp
HW.Monitor.#3: 0% GPU, 48c Temp

(for both type of hashes)

Thanks in advance !
M.
