Cost of Distance Runs Very slow

It is taking my COST of Distance (COD) 15 hours to run where it once took 32 minutes for the same data. The differences are that before the input was in native, GRID, format and now I'm using Tiff for input and output. I find it hard to believe that it would take 15 hours just to convert input data to native scratch files and back again for output. Does it speed up COD if I input 0/1 raster rather than null,1 rasters? Does it affect the speed if I am using 1, 2, 4, 8 or 32 bit files as .tif input?

Can anyone provide some insight as to how to optimize my input rasters for fastest COD processing?
