IMP is a very large and complex piece of software... so you'll have to be more specific - *what* is slower? Benchmarking, as Riccardo suggests, is one option - another would be to profile your code.

What do you mean by "Release" flag? If you mean the cmake build type ("-DCMAKE_BUILD_TYPE=Release") then that doesn't do a whole lot (IIRC, maybe some slightly different compile options on Linux; on Windows it'll change which C runtime you link against). What will make the most difference is what IMP check level you build with; if you use -DIMP_MAX_CHECKS=INTERNAL then the internal checks will definitely slow things down.
