That 256k has to hold the program that the SPE is running, as well as all the data. For fast DMA, though, your data is probably double-buffered so divide your data space in half, and hey, you might want a little space for stack / other dynamic memory usage.
Suppose your program is 48k, you use 32k of memory dynamically, that leaves 172k for data, which is double-buffered, which means the program can only process 86k of data at a time.
But it sure can do it fast.
