> but devices with slow SoC are slow even with plenty of free space. We'd find during initial development (i.e., raw, bare Android) that the initial bring up would have good-to-excellent performance, but as the storage began to fill (more "stuff" in the baked-in system/cache partitions, user-installed apps, etc.) it would lag more and more. You'd be surprised how in the early kernels (2.6-3.x series) "iowait"s would slow everything down, UI included, and not just loading speed of apps and such.
