B4R Question B4R compilation time

I noticed on compilation of B4R project that when log writes "using previous compiled version of . . . ." is faster than without it!
It is randomly happen, so slow compilation and fast compilation happened for same project randomly!
Can I force compiler to used "using previous compiled version of . . . ." almost of compilation tries.

Or any other alternative to make it fast.

My observations with B4R compilation are:
1)The first time when the project is launched it takes more compile time (actually Arduino compiler )
2)If you change the build options it takes longer to compile
3)If you clean the project it takes longer to compile
4)After upgrade from Arduino 1.6.x to 1.8.x the compilation time has drastically reduced
Actually B4R is very fast, it is the Arduino compiler which is responsible for compile times.
