wrt the question:
Very large strips and or tiles are used by people who expect that it will increase the performance of their application in some sense, and yes there might be some gain.Most computers can handle MB easily (even
Even now, most (Intel) CPUs have L2 caches optimized for looping through no more than 256k data at a time. Even if more data is read into RAM, the processing loops should usually not consume more than about 128k and performance definitely drops off once the working set exceeds 256k.
The law of diminishing returns is always present, and given L1, L2, and (possibly) L3 caches, there is a diminishment whever there are accesses to the next level of cache, or main memory.
P.S. I live in Texas, where bigger is always assumed to be better.
