Pipe is -very- slow

[Mem5]

Hi,

I ran cudahashcat v1.37 on a small dic, and I had the message "ATTENTION!  The wordlist or mask you are using is too small....."

Ok. however it tooks ~10 seconds :

Code:

cudaHashcat-1.37>cudaHashcat64.exe -w 3 -m 0 hash.txt *.dic .. Started: Wed Dec 02 22:05:33 2015 Stopped: Wed Dec 02 22:05:43 2015 -> 10 sec

Then I piped with hashcat 0.50  ; it tooks 2 minutes with a huge drop speed (sometimes 0 H/s, sometimes 300kH/s, instead of Mh/s without pipe)

Code:

hashcat-0.50>hashcat-cli64.exe --stdout *.dic | d:\cudaHashcat-1.37\cudaHashcat64.exe -m 0 -w 3 hash.txt Starting attack in stdin mode...
