The difference here is that read access to data/programs on an SD card is about twice as fast as JFFS2 (and incurs little processor overhead, whereas JFFS2 tends to occupy the processor 100%), and write access is about 15 times faster than JFFS2. I doubt the speedup is due to the presence of swap. > Regards, > > Tomeu > >> Please remember that the XO uses the processor that gave OLPC >> the most performance/power available 1.5 years ago.
