Some compiled languages are faster, some aren't. Speed of execution is largely related to the optimizations the interpreter / compiler can do, and in many practical cases the qualities of the default library. The other problem is that many interpreted languages are implemented in C leading to the usual performance implications of inner-platform effect. Another problem is the underlying CPU architecture, the vast majority of CPUs are designed to execute C-like languages.
