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.
