C++ compilers?

I am running an intel dualcore2 machine and using gcc ( ubuntu linux ) to do a c++ program. Is gcc making full use of the both cores or is it just using the one?


I ran the same thing in windows, and windows was 2min33sec while gcc was 53sec


thanks

He's probably not making full use or any use of the both cores ( its hard to say for sure because other things might slow down the execution of the program ). The compiler needs to be optimized to do that otherwise it'll work with a single core.
