Thank you. My English is not very good. So from what I understand, you are saying that productivity has not direct relationship to the programming language? Based from your comment, I did a little research. http://www.codinghorror.com/blog/2005/08/are-all-programming-languages-the-same.html Will you please point me to the source of your comment? Anyhow, I was not talking about productivity. I was trying to say measuring the web framework in "number of lines" in 2 different languages is almost pointless...esp. when it is used as a reference on performance. In Ruby, I know you can increase the script's performance by writing an extension in C. But then, is it necessary? One can obtain this increase of performance by running the program in different hardware (ie: 386 vs 486 vs core 2 dual ) > I am not sure this analysis is correct: typically, if you have a > library with a good implementation efforts have gone into it to > provide a good interface and to optimize it. You are right. I love libraries/OOP... I cannot imagine if I have to write EVERY routines myself in order for my script to work. But what if it is an mission-critical scenario? First, I prob. shouldn't use Ruby to begin with. Second, if I have to use Ruby, in order to gain back few extra cycles, I might need to write my own extension in C instead of using "standard libraries". I am already way off the original topic. Sorry.
