Thread: Pipe is -very- slow
Post: RE: Pipe is -very- slow
| It's a potential workaround, not a magic fix. Pipe incurs more host-device transfers and is more sensitive to PCI-e bus speed & latency.
You should be using cpu hashcat for this attack. |

Thread: Piping speed from statsprocessor to oclhashcat
Post: RE: Piping speed from statsprocessor to oclhashcat
| it's not that the cpu is too slow, it's that you're constantly having to make large transfers from the host to the device. |
