There are 1000 milliseconds in each second.  Thus, if GenRocket can generate 10,000 rows per second on an older, slower computer, then GenRocket is generating about 10 rows per millisecond.


Also, a CPUs clock speed is typically measured in megahertz or gigahertz. One megahertz is equal to one million cycles per second, while one gigahertz equals one billion cycles per second. This means a 1.8 GHz processor has twice the clock speed of a 900 MHz processor.


So, if you take a 1.5 GHZ CPU (1.5 B\billion cycles per second and divide that by 10,000, you get 150,000 cycles or 150,000 things the OS can do simultaneously in about 1 second; so, loading a Scenario should only take a few milliseconds in the 1 second slice amongst many other tasks; the slowest of which is loading the Scenario into memory from SSD.


Other factors also contribute to the overall performance of a computer. Examples include the number of processors, the bus speed, cache size, speed of the RAM, and HDD or SSD speed. Therefore, while the processor’s clock speed is a significant indicator of how fast a computer is, it is not the only factor that matters.
