Out of Order Benefits
A few months ago I wrote about some experiments to see how fast modern CPUs are at doing high-precision math such as is used in cryptography and high-precision fractal calculations. I recently read an article that claimed that out-of-order processors … Continue reading

Fractal and Crypto Performance
There was some recent interest in what type of computer would run Fractal eXtreme’s deep zoom calculations fastest (and cheapest) so I wrote a benchmarking tool that isolates the inner calculations for more accurate measurements and arranged to have it … Continue reading

Faster Fractals Through Better Scheduling
Performance improvements can come from many directions including better algorithms or micro-optimized inner loops. In this case I got a worthwhile speedup by working better with the Windows thread scheduler.
