Executable runs very slow, < 1000/s

[The-Z-Machine]

I am getting sub 1000 attempts/sec. How can I speed it up? I have tried various number of threads, but it doesn't speed up above 1000.

Example:
.___ _____ .__
______ | _// _____||____
____ \ / __ |\ \ __ \ ___
| |> > // | | | | | / | |> >
| /_ | || || || /
|| / || 2.0.1

I have an older laptop. Core i7-6820 at 2.4GHz. w/ 16GB memory.

Using the same setup i reached really more than that can you share the command you are using please ?

[The-Z-Machine]

Here's the command:

pdfrip -f Andy.pdf -n 8 wordlist rockyou.txt

[The-Z-Machine]

If I use this command, I get about the same speed:
pdfrip -f Andy.pdf range 00000 99999

If I put a simple password on a PDF, I can get it to work, so I know the cracking attempts are valid and can be successful It's just too slow to be useful for me.

You need to specify the number of cores too. Please try pdfrip -f Andy.pdf -n 8 range 00000 99999. Where 8 is the number of threads. I can see that this information is not mentioned clearly in the ReadMe. You can change the number of threads till you get the maximum OPS.
Edit :
I can see that you added the number of thread there so either your CPU is already at 100% usage or you need to change the number of threads to something close to your CPU logical cores number.

Still under 1000/s. There were reports of 50k/sec. Is my processor simply that slow?

[WMordy]

Try a bruteforce with default-query instead of wordlist and check the OPS. If the default-query gives much better results this might be a disk issue

[The-Z-Machine]

No love.

pdfrip -f Andy.pdf -n 8 default-query --max-length 8

200k years! That's a long time!

Well the operations per second that matters. This is a CPU issue if your CPU is already at 100% check what other apps are concurring on computing time. I have the same CPU and I got better results this can only means that something is blocking your process from getting all CPU it needs

[The-Z-Machine]

PDF Rip is taking 72% of CPU, which seems to max out at 75% total. Hmmm, I wonder if I've throttled it for some reason.

[The-Z-Machine]

maybe I'll restart and try again. I'll look at the BIOS settings.

[WMordy]

Okay and try with lower thread numbers i guess this CPU have 4 logical cores so having 8 might be more than needed try with 4 threads too.
