writes out plain Javascript, no WebAsm: emcc -O3 -sWASM=0 [.cpp and .c files…] SVD time 6.7 seconds. Wow! Plain Javascript almost as fast as compiled, highly optimized C code? (Ok, 6.7/4.4 = 1.52 ~= 50% slower… but, still… wow. ) If you do your math “the other way” (4.4/6.7 = 0.66) you can say that
