Composer XE 2013 SP1 Update2 is very slower

Hi,

I updated the Intel Fortran Compiler to SP1 update 2 (SP1.2.176) recently. I tried to compile my code using this new update. Compared with the previous compiler (XE 2013 Update 5  - 2013.5.198), it was found that the new update took about two time longer to compile the same code and generated the executable which is also about two times larger than the executable generated by using the previous version. The executable also runs slightly slower than before. Any idea or any settings I should change to use the new compiler?
