Dear all,

 I am using RegCM4.4 rc22 for model run over India using HadGEM2 RCP 4.5 dataset. Run was tried for 60km and 25 km. Model is taking 1 hour to complete one day for 25km run and 45 minutes for 60 km run. I have to run the model from 1971-2100. Can anyone suggest the reason why the model is taking so much time for a day. Is there a way to reduce the time taken by the model?

Kindly give suggestions regarding the issue.

Thanks and regards
