i have a project which was compiled and running on v5.4. Now i try to run the same in v6.1 then the performance issue is coming that the product is running very slowly. I have recompiled entire project in v6.1 and then tried again, now the performance improoved bit, but not like v5.1. Why the same project is behaving like this. I tried with a test program like above, there is a significant difference in performance betwen v5.4 and v6.1. What should i do to achieve the same performance in v6.1 like in v5.4.
