Due I2C performing slower

Hi everyone I am using MPU9150 and the I2CDev Lib (https://github.com/sparkfun/MPU-9150_Breakout). I tried to just read the sensor data getmotion9 using both due and mega. The mega did it in abt 0.038 s while the due is taking abt 0.3 s. Please suggest me some ideas.

Check to see if the I2C is configured correctly.

The Due is a faster processor than the Mega, but if I2C is set to the same speed on both, it won't necessarily be any faster.
