Did 1000000 long long multiplies in 2.03297 seconds. Did 5000000 long long multiplies in 9.61538 seconds. Did 10000000 long long multiplies in 17.9121 seconds. Did 50000000 long long multiplies in 98.341 seconds. but perhaps a comparison of long-operations and long-long-'s would be more interesting? after all we already know that different CPU's will perform differently.. what is really interesting is how the performance on the same CPU declines if long's are replaced by long-long's. i might do that tomorrow. g'bye.
