MPC5777C hw floating point execution time

hello..

 

i'm running a few lines of code and noticed the execution of the floating point math is pretty slow.. costing 10us to do one integer x float.. i'm using the DS for S32 power R17.1 and the Target Processor setting page of the property has the "Use hardware floating point" checked.. the user manual says single precision is fully supported but didn't elaborate the performance part. Any one any comments?

 

thanks
