[QUOTE="www, post: 2847119"]
Hi,

I have translated an old Fortran program into Java program, line by 
line. The Java program produces the identical results as Fortran one 
does. But Java program does I/O involved with xml parsing a lot.

Now, my customer needs information regarding how slow or fast the Java 
program is, compared to its original Fortran program. Can you provide me 
some idea on how to get such information?

To complicate my question, I hope to ignore the I/O code in Java 
program, only compare the heavy duty computation part. Because Java 
program does a lot of xml parsing, very time consuming. Fortran program 
does not. So it is unfair to include I/O portion, when compare the two 
programs. Can you also give me some idea on how to do that?

Previously, I have posted my question in different description and many 
people say that I need profiling. I use Eclipse and I know a little 
about TPTP. I don't know TPTP can provide me such information. I thought 
it provides the relative execution time of each block of code., like 
some method takes 98% time and is obviously a bottleneck.

Thank you very much.
