javascript、ruby和C性能一瞥(3) :上汇编

在博文(1)和(2)里分别用了4中方式写一个素数筛选的算法，分别是javascript in browser、node.js、ruby和c；最终的结果是c最快，node.js其次,js in b虽然也不慢，但极不稳定，所以排在第三，ruby最慢。现在我们在linux64中用汇编语言重写sieve算法，看看动用最终的武器：汇编语言，我们能不能进一步优化素数筛选算法。如果忘了算法逻辑，不要紧...

javascript、ruby和C性能一瞥(2)

好吧，最后让我们用C来实现，看看再能榨取多少性能。注意我没有改变算法，C的算法和之前的3种都是基本相同的： #include <stdio.h> #include <stdlib.h> #include <stdbool.h> #include <math.h> #include <string.h> #include <tim.....

javascript、ruby和C性能一瞥(1)

测试一下本地js、浏览器中的js以及ruby对于类似算法的性能。结果有些意外：浏览器js最快，本地其次当相差很小；ruby最慢而且不是一个数量级的；因为写的匆忙，可能有重大问题没能看出来，请各位高人不吝赐教。程序计算小于给定数n的最大素数，代码均未作优化，我们依次来看：首先是浏览器的： <!DOCTYPE html> <html> <head>...
