Some architectures like MIPS have to use code generation options that make slighly less efficient code. So there might be a _very_ small difference in efficiency. Another reason why MIPS modules are less efficient than compiled in code is that the kernel itself does never generate TLB faults on MIPS. All in all I'd say the difference is neglegtible though I didn't benchmark that yet.
