I don’t have a high traffic blog by any means. But as I mentioned in this blog post, nobody really noticed the almost identical C solution I found in the forums. I think you hit the nail on the head when you said “…nobody else appreciates this stuff.” Most programmers today are not familiar with what’s actually going on within the CPU. They don’t drop down to C to optimize performance critical code. I think modern software suffers for this.

I’d like to say that was a “clever” way of handling the problem. I’m a bit twiddler and perform lots of system level bit transformations on data…so it seemed like a logical path to me. Of course understanding the architecture of your system (ok…most everything is 64-bit these days) and optimizing your solution for it was smart. Maybe nobody else appreciates this stuff. We had a long standing solution in our office that took about .2 seconds to run — However, we found ourselves using this operation 50,000 times in succession. Now we are at 10,000 seconds. Last I checked…there’s only 60 in minute. Results took HOURS. I optimized our algorithm (via a lower level language “C”) and got the single response time down to .001 seconds. This allowed us to finish the workload (50,000 calls) in less than 1 minute. Indeed it can pay to be closer to the machine.
