If I have large amount of data as NSMutableData that is all in short Little Endian format, is there a faster way to convert it to Big Endian than looping through the data with NSSwapLittleToHost.

Yes, you can create AltiVec optimized swapping routines. AltiVec can also swap data on-the-fly within some restrictions. Note that you should still provide a C-based method that can be used on G3:s (and possibly other architectures).
