pyrit export_hashdb is SOOOOO SLOW #72

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. I add essid (one essid) and list of password (250 million of passwords),
then I run batch calculation, all runs fine ans afrer some hors the job was
completed. 
2. I export database (more than 9GByte) into cowpatty format (command
export_cowpatty), it takes about 15 minutes to complete export.
3. I export the same database in airolib format (command export_hashdb) but
pyrit is still under 30% of exporting after more than 10 hours!

What is the expected output? What do you see instead?
I see that outbut "wrote #NUMBER lines" is quite stopped, it increments
#NUMBER only every several minutes.

What version of the product are you using? On what operating system?
pirit 0.2.4 compiled on debian (Lenny) with  kernel linux 2.6.26-2-686,
the CUDA software is last release avaiable, CPU is NVIDIA 9800 GTX+

Please provide any additional information below.
htop report that CPU (Phenom2 4core) is quite free of load, instead it
shoud be have at least one core at 100%: it semms pyrit has long periond of
"sleep" and little period of "work".

htop report that there are 162 busy MB on 2GB avaiable on the PC.

Thanks for reporting. This behaviour is entirely caused by sqlite in general and
airolib-ng's database format in particular. It's not going to go away.

I consider airolib-ng to be dead
