Dctimestep performance

I’m trying to eke out the maximum performance I can get from dctimestep. The case is for annual simulation on ~6000 points and 5185 sky patches. I am using a SSD and -of binary output to speed up disc access.

I notice in the task manager that dctimestep is constantly allocating more memory during its run. I thought that if all the input files specified nrows and ncols, it would be able to allocate the memory just once. Is there something I could do here to speed it up?

Does anyone have other tips or tricks for speeding up dctimestep?

Thanks,

Nathaniel
