The NAND flash on the XO might be dragging our performance down. Possible culprits:

  • Garbage Collection Pressure steals CPU and I/O cycles.
  • Compression steals CPU cycles on file copy?
  • Long jffs2 mount time drives small children stir-crazy.
  • Complex file packing makes it too hard for Open Firmware to write to jffs2?

Things to work on:

  • Find a good experimental system for modeling XO-like performance without needing compression to fit onto the flash.
