On modern Intel parts, 32 bit integer division for Nehalem and Westmere is specified with a throughput of 5-13 cycles, and for Sandy Bridge it's specified with a throughput of 11-17 cycles. At 3 GHz, that's in the neighborhood of 3-4ns, which is damn impressive. In the height of the Netburst era (~2004), 32 bit integer division on Prescott was specified with a latency of 30 cycles, or around 11ns at 2.66 GHz. And if you go back to the original Pentium, it was specified as 46 cycles, which at 166 MHz is 277ns.
I guess what I'm saying is that division used to be a scary boogeyman, but it's not anymore. The hardware people have done their job.

I am being sponsored by Syntress since 2007! They bought me an amazing dedicated server to run catonmat on. If you're looking web services in Chicago area, I highly recommend the Syntress guys!
I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
