发帖数: 372 | 1 We know that using heap-allocated memory is slower than stack memory. Can
anyone tell me how much slower is the heap memory allocation? A numerical
analysis on a popular implementation would be terrific, e.g., linux. Another
stupid question: after memory allocation, the access to heap memory should
be as fast as to stack memory, right?
Thanks. | w*******y
