Flow Accumulation: Gaining Speed

Hello,

I need to use the Flow Accumulation tool on a relatively large DEM (30 meter cellsize) with a weight raster (cellsize roughly 900 m), which takes probably some days to finish.
Are there any means to speed up the computation proceedure?
Or do the following steps shorten the computation time?
- same cell size
- same projection
- Output float/integer

Thanks in advance
