If you are only (or mainly) interested in the times spent inside functions (and functions called inside those), you could try gprof in combination with gcc. I find it very easy to use, too. Basically I add -pg to the options for compiling and linking, run the executable, and then start gprof and look at the output. Regards, Dieter
