Hello

I ported a Windows program to my mac and realised the program that took
around 5 seconds to run on Windows now takes atleast 1 minute on my mac. It
uses alot of STL (string, vecor, map, list) but I cant imagine the STL
implementation to be that slow. So I wonder if there are any profiling tools
which could help me find out where the time is beeing spent. So far I went
on with gdb but realised it didn't really help me too much.

Any recommendations are welcome.

Regards,
John

You can start with Sampler, which is installed as part of Apple developer tools.
Beyond that, download CHUD from <http://developer.apple.com/tools/performance/>.

If you're working from the command line, then try the "-pg" option of the compiler.
Run the binary, and then use 'gprof' to look at what routines took all the time
(among other statistics). See the 'gprof' manual page.
