immediately on the Swift side, -O Optimize for Speed, since we were not concerned with memory or code size for this test. 800x800 matrix size runs in Swift: seemed to vary between 18.x to 20.x seconds. C code equiv was about 4.1 to 4.2 seconds. Recall from our prior article that JS gave performance
