I checked how long it takes to do that with Whirlpool and it was about 315ms on average (with i7-2600).

The CPU usage of one core increased to 100% during this, so this indeed is a resource intensive operation. This might result in less smooth gaming experience, particularly with low-end servers.

Just for comparison: "A PC running a single AMD Radeon HD7970 GPU, for instance, can try on average an astounding 8.2 billion password combinations each second, depending on the algorithm used to scramble them.", http://arstechnica.com/security/2012...under-assault/


In case someone cares, here's the script I used:

pawn Код:

main()
{
    new s_time = GetTickCount();

    new buffer[129];
    WP_Hash(buffer, sizeof(buffer), "password123");

    new i = 0;
    while(i++ != 65536)
        WP_Hash(buffer, sizeof(buffer), buffer);

    printf("%d", GetTickCount() - s_time);
    return 1;
}
