Did you have a chance of testing it with various real flash : old small page
nand flash, very big large page NAND (4GB), ...

May be you could update your benchmark :
http://osl.sed.hu/wiki/ubifs/index.php/Mount_results doesn't give super result :
1 second mount time on a 64 MB flash with 517.73 BogoMIPS CPU.
What will be the result for a 4GB flash ? 64 seconds ?

Did you do very intensive and long test where you can see bad block appearing on
the flash ?


Speaking of big nand, is UBI/UBI-FS free of 2GB/4GB limit ?

Is it possible to create small and fast code for read only support in 
bootloader ?
