Performance

[Abnormality]

Intel Xeon X5650: 6 cores, 12 threads. To sum up, you have two 64bit CPUs with total amount of 12 cores and 24 threads. So, install x86_64 system and use hashcat-cli64 binary with 24 threads.

What if I can't install a 64 bit system? It's a VPS so I can't do that. Any ideas?

Why couldn't you install x86_64 system on VPS ? Try your previous command with '-n 24'.

Because a friend of mine is lending it to me and I just can't reinstall everything. Any other suggestions besides -n 24?

Also note that -m 2611 is an iterated algorithm, not raw md5. Speed is at least twice as slow, maybe more.

Indeed, but I expected it to be much faster. Using Hashcat CPU on my own PC (a high-end laptop) I'm getting around 25M/s so I thought that on a VPS running that incredible processor would be much faster instead of just being twice as fast.

Well, then just start hashcat with standart amount of 8 threads (don't force number of threads with -n or --threads) and let us know how it's going.

Command was: ./hashcat-cli32.bin -m 2611 hash.txt -a 3 ?a?a?a?a?a?a

On my PC (a laptop) I'm getting

Why am I getting almost the same on a laptop than on a VPS with a business processor with much more power?

VPS are normally on a shared host with many VPS running.

[epixoip]

right. you're using shared resources, and most vps providers make heavy use of oversubscription so that they can put a large number of virtual machines on a single host. you're probably only getting 1/8 of 1 core of that "business processor."

[epixoip]

i just read back through where you stated you have "24 Intel Xeon X5650." what this probably means is that the /virtual host/ has 2x X5620, for a total of 12 physical cores and 12 logical cores via hyperthreading.

what your vps provider then does is figures out the 95%ile load over a given period to determine how many virtual machines they can squeeze onto each virtual host. typically they will determine they are able to create 2x-3x more virtual machines than the number of cores in the system -- usually counting hyperthreading "cores" as well. so on a 24 core host there are probably 48-72 virtual machines all sharing resources.
