Not sure about the stats WPA/WPA2

[handmadebots]

Ok, so I've heard a lot of good things about hashcat, so I wanted to give it a try. I got a 4-way handshake, I've made it in the final version *.hccap

I have a pretty new laptop, i7, NVIDIA GeForce 740 2GB, etc

Now... I have a wordlist, and I am using this command (windows 8) to try a dictionary attack:

cudaHashcat64.exe -m 2500 -u 4096 c:\Hacking\wireless\tp-link.hccap c:\Hacking\cracking\wordlist\Romanian.dic

and I get the following results

Hashes: 1 total, 1 unique salts, 1 unique digests
Bitmaps: 8 bits, 256 entries, 0x000000ff mask, 1024 bytes
Rules: 1
Applicable Optimizers:

* Single-Hash
* Single-Salt

This means that 16513 passwords are tried per second ?
It's pretty good, in comparation to aircrack, even though I've seen some youtube videos, where the speed was 70k (almost the same GPU card), and it's real big difference.

This was the dictionary attack.

Trying it with mp64, I get better results, but I am not sure if I understand correctly, anyway, here is the bruteforce attack with 6 letters:

mp64.exe ?l?l?l?l?l?l | cudaHashcat64.exe -m 2500 c:\Hacking\wireless\tp-link.hccap

I get this results:

From this stats, I understand that 308915776 were processed in ... 1 minute and 10 seconds ?!

It's a really big difference from dictionary to bruteforce.

Did I get it wrong or... I am way to far from the truth ?
