Compressor taking too much time while making DCP File

hi... friends
I am using qube master xport plugin in compressor for making DCP file. when i import a Apple prores 1920/1080 (HQ) MOV file in compressor and convert in DCP its taking 2 hours 30 minutes for 20 minutes video file. My question is that it's normal time or I did something wrong ?
Compressor Aspect Ratio Flat 1998/1080
